Answer:

-4

Explanation:

In this case, rate of change will be equivalent to the gradient of the line.

Standard form of Equation of Line:

y = mx + c

where

m = Gradient

c = y - intercept

From the given information, we can substitute x = -1 and y = 0, and c = b = -4 (y-intercept) to find m (Gradient)

0 = -1m - 4

m = -4

Therefore, the rate of change is -4.
