Answer:
y = 5x - 7
Step-by-step explanation:
(x₁ , y₁) = ( 2 , 3) & (x₂ , y₂) = (-1 , -12)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{-12-2}{-1-2}\\\\=\frac{-15}{-3}\\\\=5[/tex]
m = 5 & (x₁ , y₁) = ( 2 , 3)
Equation of the line: y - y₁ = m(x -x₁)
y - 3 = 5(x - 2)
y - 3 =5x - 2*5
y - 3 = 5x - 10
y = 5x - 10 + 3
y = 5x - 7

Answer:
m∠1 = 140°
m∠2 = 40°
m∠3 = 65°
m∠4 = 75°
m∠5 = 115°
Step-by-step explanation:
We will use a few different methods to find the angles:
A triangle's angles will always add up to 180°. With this information, we can find the last angle of the triangle on the left:
∠1+∠2+∠3=180°
60+80+∠3=180°
Let x represent the value of ∠3. Simplify addition:
[tex]140+x=180[/tex]
Subtract 140 from both sides:
[tex]140-140+x=180-140\\\\x=40[/tex]
The unknown angle is 40°. With this information, we can find the
m∠1:
m∠1 and the 40° we just found are supplementary angles, which means that their measures will add up to a total of 180°.
∠1+∠2=180°
Insert the value we know:
40°+∠2=180
Let x represent the value of ∠2. Subtract 40 from both sides:
[tex]40-40+x=180-40\\\\x=140[/tex]
There fore:
m∠1=140°
We can use this same rule to find the m∠2:
∠1+∠2=180°
or, we can use the vertical angles rule. The first angle we found (Which is 40°) is a vertical angle to m∠2, so they have the same value. Therefore:
m∠2=40°
To find m∠3, we need to find the other missing angle in the middle triangle. Use the supplementary angle rule, since the missing angle is supplementary to the angle that is 105°:
∠1+∠2=180°
Insert the known values, substituting x for the unknown angle:
[tex]x+105=180[/tex]
Subtract 105 from both sides:
[tex]x+105-105=180-105\\\\x=75[/tex]
The unknown angle is 75°. Now find m∠3, knowing that triangles add up to 180°:
m∠2+m∠3+75=180
Insert the m∠2, make m∠3 be x:
[tex]40+x+75=180[/tex]
Simplify addition:
[tex]115+x=180[/tex]
Subtract 115 from both sides:
[tex]115-115+x=180-115\\\\x=65[/tex]
Therefore:
m∠3=65°
To find m∠4, use the vertical angle rule.
Therefore:
m∠4=75°
To find m∠5, we could find all triangle measures of the least triangle, or we can use the following:
An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees.
The m∠5 is the exterior angle, and the opposite interior angles are 75° and 40°:
[tex]75+40=115[/tex]
Therefore:
m∠5=115°

Michelle has 3 3/8 cups of cereal. A serving of cereal is 3/4 cup. How many servings of cereal does Michelle have ?
Answer:
4.5
Step-by-step explanation:
(3 3/8) / (3/4)= 4.5
The amount of servings of cereal that Michelle have is 4 1/2 servings of cereal
From the question, we are told that a serving of cereal is 3/4 cup, this can be expressed as:
1 serving of cereal = 3/4 cups
If Michelle has 3 3/8 cups of cereal, this can be expressed as;
x = 3 3/8 cups of cereals
Divide both expressions
1/x = 3/4 * 8/27
1/x = 6/27
x = 27/6
x = 9/2
Hence the amount of servings of cereal that Michelle have is 4 1/2 servings of cereal

Use the following rules to graph and by label the ordered pairs on a coordinate grid with at least 4 points on the coordinate plane:
1. Maddy wrote a pattern for the
x coordinates starting at 3 and followed the rule “add 2.”
2. Ted wrote a pattern for all the y coordinates starting at 0 and followed the rule “add 4.”
Maddy's rule for obtaining the x-coordinate values and Ted's rule for
obtaining the y-coordinate values combine to form a linear graph.
Reasons:
Please find attached the graph with labelled ordered pairs created by Maddy's and Ted's rules.Method by which the graph is formedThe given rules used to graph the equations are;
Maddy's rule for the x-coordinate values = x + 2, where, x ≥ 3
Ted's rule for the y-coordinate values = y + 4, where, y ≥ 0
Therefore, the following table of values can be generated;
[tex]\begin{tabular}{|c|c|}x&y\\3&0\\5&4\\7&8\\9&12\\11&16\end{array}\right][/tex]
The first difference of the y-values is constant and the difference in the x-
values is also a constant, therefore, the data represents a linear function
and the graph is also linear.
Using the above table of values obtained from Maddy's and Ted's rules, the
graph of the ordered pair can be plotted by entering the values in MS

Reasoning Graph the set of ordered pairs (0, 2). (1.4), (2,6). (3.8). Determine whether the relationship is a linear function Explain how you know.
Answer:
No, it does not. See below.
Step-by-step explanation:
Lets find out the linear equation that passes trough (-2, 0) and (0, -6).
We know every linear equation has the form: y = mx + b
Where m is the slope on the curve and b the independent term.
We know that, given 2 points (x1,y1) and (x2,y2) we can find the slope m as:
m = (y2-y1)/(x2-x1)
In our case lets replace (x1,y1) and (x2,y2) by (-2, 0) and (0, -6) (notice it could be done in the inverse sense where (-2, 0) is (x2,y2) and (0, -6) is (x1,y1) ). So, our slope is:
m = [-6 - 0] / [0 - (-2)]
m = -6/2 = -3
So, we have a downward linear function with slope -3, this is:
y = -3x + b
Now, for finding b just replace any of the 2 points given in the equation. Lets replace (-2, 0):
0 = -3(-2) + b
0 = 6 + b
Subtracting 6 in both sides:
-6 = b
So, our independent term is -6 and the function is:
y = -3x - 6
Now lets see if this linear eqution passes trough (2,6). If it does, we can replace the values on the equation. Replacing x by 2:
y = -3(2) - 6 = = -6 - 6 = - 12
So, in our equation, we x is 2 y is -12, and not 6 as in the point (2,6). So, our equation does not passes trough (2,6)
