Question

Which equation represents the line of best fit shown?

Answer 1

A) y=19x-810

Explanation:

This line of best fit is moving downward, or negative. The last number in the equation represents where the line intercepts the y axis, hense the y-intercept. Which is 810.

Now there are only two equations in which 810 is last in the equation. And B) would have the line moving upward, so A is the answer.

Hope this helps!

Answer 2

b is the correct answer.

Explanation:

Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.
