The slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.

What is the slope intercept form of a line?
The line with m as the slope, and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, c, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Given, the equation of the line is 2y = 6x - 12
Dividing the given equation by 2 we get, y = 3x - 6 ⇒ y = 3x + (-6)
Comparing the equation with the standard form of slope intercept form of a line as established in literature, we have:
Slope = m = 3 and y-intercept = c = -6
Thus, the slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.

The relation is a function if every ordered pair has one value of x, which means x does not repeat

Let us study each relation

a) {(5, 1), (-2, 4), (1, 1), (5, 2)}

Since each ordered pair has a different value of x

There are 2 ordered pairs that have x = 5

This relation is not a function

b) {(1, 4), (-2, 2), (5, 1), (-6, 2)}

Since no repeated x in the ordered pairs

Then the relation is a function

c) There are 2 ordered pairs with x = -2

It is not a function

d) There are 2 ordered pairs with x = 1

It is not a function

The answer is b

Answer:

[tex]f(x)=x+2[/tex]

Step-by-step explanation:

Given parameters:

Therefore, there are two points on the line:

The linear relationship between the x and y values is:

[tex]\implies f(x)=x+2[/tex]

To prove this algebraically, define the points:

Find the slope of the linear function by substituting the defined points into the slope formula:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{2-0}=\dfrac{2}{2}=1[/tex]

Substitute the found slope and one of the points into the point-slope formula to create a linear function that satisfies the given parameters:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-2=1(x-0)[/tex]

[tex]\implies y-2=x[/tex]

[tex]\implies y=x+2[/tex]

Hence proving that the linear function is:

[tex]f(x)=x+2[/tex]

Slope = 2

The slope of coordinates ( 20 , 15 ) and (30 , 35) = 2

Here given two points (20, 15) and (30 , 35)

Formula to find slope = y2 - y1 / x2 - x1

                                    = 35 - 15 / 30 - 20

                                    = 20 / 10

                                    = 2 / 1

                                    = 2

The rate of change of the area is -80.5 [tex]inches^{2}[/tex]/sec.

Given:

A right triangle has legs of 21 inches and 28 inches whose sides are changing.The short leg is decreasing by 2 in/sec and the long leg is shrinking at 5 in/sec.

Let's set the two legs as a and b, so the lengths are:

a = 21 - 2t

b = 28 - 5t

The area is:

area a = ab /2

= (21 - 2t) (28 - 5t)/2

= (588 - 105t - 56t + 10[tex]t^{2}[/tex]/2

a = 5[tex]t^{2}[/tex] - 161t/2 - 299

The rate of change of the area is:

da/dt = d(5[tex]t^{2}[/tex] - 161t/2 - 299)/dt

da/dt = 10t -161/2

The equation of the model is 42 × ? = 5,964.

Here we have to find the equation of the model

Area of a rectangle:

The area of a rectangle is equal to the product of length into breadth.

Area of rectangle = length× breadth

length =?

breadth = 42

Area = 5,964

So we have an equation:

?× 42 = 5,964

a) 5,964/ 42 = ?

5,964 = 42 × ?

So it is correct

b) 5,964-? =42

5,964 = 42 + ?

So it is not correct.

c) 5,964/ ? = 42

5,964 = 42× ?

So it is correct

Equation of line in ordinary form: y = 2x+0

Equation of  line  in standard (general) form: 2x - y = 3

What is Slope?

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

a) Ordinary form =>

Slope Intercept Form:

y = mx+b

where m is the slope of the line

(Δy/Δx)

and b is the y-intercept.

For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x, -6 for y, and solve for b.

-6 = 2(-3) + b

-6 = -6 + b

6 - 6 = b

b = 0

The equation in slope intercept form is

y = 2x+0

b) Standard form =>

Point Slope Form:

(y - y1) = m(x - x1)

Where m is the slope of the line

(Δy/Δx), y1 is the y coordinate of a point, and x1 is the x coordinate of a point.

For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x1, -6for y1,

(y - (-6)) = 2(x - (-3))

Standard Form:

Ax + By = C

Where A, B, and C are integers. To write an equation in standard form, rewrite the equation in point slope form so that it fits the formula for standard form.

(y - (-6)) = 2(x - (-3))

(y + 6) = 2(x + 3)

y + 6 = 2x + 3

2x - y = 6 - 3

2x - y = 3

Hence, Equation of line in ordinary form is y = 2x+0

Equation of  line  in standard (general) form is 2x - y = 3

Answer:

Line A: 4

Line B: -2

Step-by-step explanation:

Note: gradient means slope, or m, in this context

To find the slope of a line, use the formula:

[tex]m = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]     where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points on the line

Line A has points (2, 2) and (3, 6). To find the slope of the line, simply plug these values into the formula for m :

[tex]m_{\mathrm{line \, A}}=\dfrac{6-2}{3-2}=\dfrac{4}{1}=4[/tex]

So, the slope, or gradient, of line A is 4.

Next, do the same thing for Line B.

Find two points on the line:

(0, 8) and (1, 6)

And plug these values into the formula:

[tex]m_{\mathrm{line \, B}}=\dfrac{6-8}{1-0}=\dfrac{-2}{1}=-2[/tex]

So, the slope, or gradient, of line B is -2.

In order to find the quadratic equation, let's use the vertex form below:

Where the vertex is located at (h, k).

So, if the vertex is (h, k) = (-4, 2) and using the point (x, y) = (-4, 0), we have:

Since the final statement is false, it's not possible to have a quadratic function with vertex (-4, 2) and with the point (-4, 0).

If we use the point (4, 0) instead, we would have:

So the equation in this case would be:

The empty spaces would be filled with the values -1/32, -4 and 2.

The equation of the volume function is V(x) = 1/3(x + 4)²(x - 1)

The given parameters are

Radius, r = x + 4

Height, h = 5 units less than the radius

This means that

h = r - 5

So, we have

h = x + 4 - 5

Evaluate

h = x - 1

The volume of a cone is calculated as

V = 1/3πr²h

Substitute the known values in the above equation

V = 1/3 * (x + 4)² * (x - 1)

This gives

V = 1/3(x + 4)²(x - 1)

Express as a function

V(x) = 1/3(x + 4)²(x - 1)

Hence, the function is V(x) = 1/3(x + 4)²(x - 1)

From the given parameters using Pythagoras theorem, we can say that No, the ladder will not reach a window that is 21.5 feet above the ground.

We are told that the ladder is 25 ft and leans against the wall and so this will be the hypotenuse of the right angle triangle formed with the building.

The horizontal distance from the base of the ladder to the building is 15 ft. Thus, this will be the base or adjacent side of the triangle.

I have drawn a triangle to show this measurements and so we can use Pythagoras theorem to find the vertical height from the top of the ladder to the ground.

BC² = AB² +  AC²

25² = 15² +  AC²

AC² = 25² - 15²

AC = √(25² - 15²)

AC = 20 feet
