Determine the equation of the line that passes through the given points. (If you have a graphing calculator, you can use the table feature to confirm that the coordinates of both points satisfy your equation.) (3.5, 8.2) and (2, 7.3) a. y = -0.6x - 6.1 b. y = 0.6%-6.1 C. y=-0.6x + 6.1 d. y = 0.6x + 6.1 Please select the best answer from the choices provided A B C D
Answers
The choice (d), y = 0.6x + 6.1, is the most accurate match when comparing this to the possible answers. Although near but not identical, the line's slope. y = -0.9x + 11.35 is the right response.
What does slope mean?Slope is what? . The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.
Describe a slope example?
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
To find the equation of the line that passes through the given points, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope of the line and b is the y-intercept.
First, we can find the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1) = (7.3 - 8.2) / (2 - 3.5) = -0.9
Next, we can plug in one of the points and the slope into the equation of a line to find the y-intercept:
y = mx + b
8.2 = -0.9 * 3.5 + b
8.2 = -3.15 + b
b = 8.2 + 3.15 = 11.35
So, the equation of the line that passes through the points (3.5, 8.2) and (2, 7.3) is y = -0.9x + 11.35.
Comparing this to the answer choices, the closest match is choice (d), y = 0.6x + 6.1. The slope of the line is close, but not exactly the same. The correct answer is y = -0.9x + 11.35.

Step-by-step explanation:
If the percent error is 6% (0.06 in decimal form) of 600 gr, then the error is :
0.06 * 600 gr = 36 gr
Therefore the actual mass of the book is between 600 - 36 = 564 gr and 600 + 36 = 636 gr.

a.) (2, -4)
b.) (-4, -4)
c.) (-4, 0)
d.) (-4, -2)
Answers
When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.
Remember: (-6, -4)
X = -6
Y = -4
If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)

Which table represents a direct variation? Table A x 4 6 8 10 y 7 9 11 13 Table B x 4 6 8 10 y 12 18 24 30 Table C x 4 6 8 10 y 1 3 5 7 Table D x 4 6 8 10 y 3 3 3 3 Table A Table B Table C Table D
Answers
Answer:
We conclude that 'Table B' represents a direct variation.
Step-by-step explanation:
We know that when y varies directly with x, the equation is
y ∝ x
y = kx
k = y/x
where 'k' is called the constant of proportionality.
Table A
x 4 6 8 10
y 7 9 11 13
Finding k for all the pairs of x and y
k = y/x
k = 7/4, k = 9/6 = 3/2, k = 11 / 8, k = 13/11
As constant of proportionality 'k' does not remain constant.
Hence, table A does not represent a direct variation
Table B
x 4 6 8 10
y 12 18 24 30
Finding k all the pairs of x and y
k = y/x
k = 12/4 = 3, k = 18/6 = 3, k = 24/8 = 3, k = 30/10 = 3
As the constant of proportionality remains constant.
Therefore, the value of k = 3 for all the points in the table.
Hence, table B represents a direct variation.
Table C
x 4 6 8 10
y 1 3 5 7
Finding k all the pairs of x and y
k = y/x
k = 1/4, k = 3/6 = 1/2, k = 5/8, k = 7/10
As the constant of proportionality 'k' does not remain constant.
Hence, table C does not represent a direct variation.
Table D
x 4 6 8 10
y 3 3 3 3
Finding k all the pairs of x and y
k = y/x
k = 3/4, k = 3/6, k = 3/8, k = 3/10
As the constant of proportionality 'k' does not remain constant.
Hence, table D does not a direct variation.
Therefore, we conclude that 'Table B' represents a direct variation.

Look At the y over x. X is how many places you move on the x-axis. Y is how many places that you move up. So you would repeat that where the Y intercept is.
Step-by-step explanation: for example: y=2x+1. You would move up 2 places and over on the X axis one place, and since 1 is the Y-intercept that is where it would intercept on the Y-axis.

The equation of line q is 5y - 4x = 10. Write the standard fom of the equation of the line that fits the following description:
parallel to q and passes through the point at (-15, 8)
Answers
===================================================
Explanation:
The given equation is the same as -4x+5y = 10
It is of the form Ax+By = C, where A = -4, B = 5, C = 10
Anything parallel to Ax+By = C is of the form Ax+By = D. The only difference is the C has changed to a D.
This means anything parallel to -4x+5y = 10 is -4x+5y = D, where D is not equal to 10, but it could be any other number.
Plug in the coordinates of (-15,8) to find the value of D
-4x+5y = D
-4(-15)+5(8) = D
60+40 = D
100 = D
D = 100
We have -4x+5y = D update to -4x+5y = 100
The equation -4x+5y = 100 is parallel to -4x+5y = 10, and it goes through (-15,8)
Parallel lines have the same slope, but different y intercepts.
Note how Ax+By = C has a slope of m = -B/A. This means A cannot be zero.
Solve for x: 6x + 2 = 4x - 1
Answers
6x+2=4x-1
6x-4x+2=-1
Then you move the constant to the right side and change its sign so its
6x-4x=-1-2
After that you subtract the like terms which is 6x and 4x
So its
2x=-1-2
Then you calculate -1 and -2
So it turns into -3
2x=-3
After that you divide both sides by the equation by 2
So your final answer is going to be x=-3/2

Suppose there is 1.4 a drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 64.2, what will be the temperature when the plane reaches an altitude of 8000?
Answers
Answer:
The temperature will be 53
Step-by-step explanation:
Here, we are told that there is a temperature drop for every 1000 feet rise into the sky
Now, for 8000 ft, there will be 8 drops
Each drop is 1.4;
So 8 drops will be 1.4 * 8 = 11.2
So to get the current temperature, we simply go on to subtract from what we had initially
Mathematically, that will be
64.2 - 11.2 = 53

Write and solve an equation to find the size of Falls Lake.
Answers
Answer:
f = 4d -400
Step-by-step explanation:
First, let's make some variables.
f = size of Falls Lake
d = size of Lake Drummond
d = (1/4)*f + 100
We can now rearrange the equation to find the size of Falls Lake.
d - 100 = (1/4)*f
4d - 400 = f
f = 4d - 400

Step-by-step explanation:
Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake
A. How much flour did she use for both cakes?
We solve the above question by adding up the pound of flour used for both cakes.
2/5lb Of flour + 3/4lb Of flour
Lowest common denominator = 20
= 8 + 15/20
= 23/20
= 1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
This is calculated as:
5 lb - 1 3/20 lb
= 3 17/20 lb
