Which line is the best model for the data in the scatter plot?

B

Step-by-step explanation:

The line that is the best model for the data in the scatter plot must pass through as mane points as it is possible and the rest points have to be in equal amounts under the line and over the line.

Model A: Line passes through 2 points, 7 points are over the line and 3 points are under the line.

Model B: Line passes through 2 points, 5 points are over the line and 5 points are under the line.

Model C: Line passes through 2 points, 6 points are over the line and 4 points are under the line.

Model D: Line passes through 2 points, 3 points are over the line and 7 points are under the line.

Only model B matches the conditions.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

thats one
