Answer:
the desired equation is y = -2x + 1
Step-by-step explanation:
As we go from (-2, 5) to (0, 1), x increases by 2 and y decreases by 4. Thus, the slope of this line is m = rise / run = -4 / 2, or m = -2.
Starting with y = mx + b, insert the knowns:
1 = -2(0) + b. Then b = 1, and the desired equation is y = -2x + 1.
