Use 2 points on the line to find the slope.

(0,0) and (4,-16) slope = change in Y over the change in X

Slope = ( -16 - 0) / (4-0)

Slope = -16 / 4

Slope = -4

The equation would be 4) y = -4x

Answer:

4) y = -4x

This is the answer to number 4! The other helper explained it great but if you still are confused and need extra help let me know!(:
