Answer:
-4
Step-by-step 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.
