Which equation best represents the line of best fit for the scatterplot? a) y = 2.5x + 25 eliminate b) y = −2.5x + 20 c) y = −0.05x + 20 d) y = −0.005x + 22.5

The right answer is: D\

Because y = −0.005x + 22.5

Choose 2 points to find the slope: (1500, 12.5) and (1000,15)

15 − 12.51000 − 1500 = −0.005 

Also, the y-intercept is approximately 22.5.

y = −0.005x + 22.5 is correct, which is D.

A) 144.44 sq inches i believe
