Question

Which function is best represented by this graph?

y = 2x + 8

y=−8x+8

y=−2x+8

y=−2x+4

Answer 1

y = -2x + 8.

the line is going down meaning your m/slope is negative, and it decreases by 2. m = -2.
the line passes y = 8 at x = 0, making it the y intercept.

Answer 2

-2x + 8

Explanation:

8 is y intercept. 2 units down and one to the right. -2/1 so -2
