Answer:
y = -4x - 1
Step-by-step explanation:
As we move from the point (-2, 7) to the point (3, -13), x increases by 5 and y decreases by 20. Hence, the slope of this line is m = rise/run = -20/5, or -4.
Starting with the slope-intercept formula for a straight line:
y = mx + b. We substitute -4 for m, -13 for y and 3 for x:
-13 = (-4)(3) + b, so b = -1, and the desired equation is:
y = -4x - 1
