Question

What is the best fit equation for the trend line in the scatter plot?

A. y = 3x + 8

B. y = -1/3x + 8

C. y = -3x - 8

D. y = 1/3x - 8

Answer 1

The answer is D y= 3x-1 because the slope is 3 and the y-intercept is -1

Answer 2

B the line goes down so its a negative gradient

and you do rise which is -1 over run which is 3
