The difference between the rate of change of B and the rate of change of A is 15.
<h3>
How to get the difference in the rates of change?</h3>
First, we need to get the two rates of change.
We have two linear functions.
A: y = 35*x
For function A the rate of change is the slope, wich is 35.
Function B is graphed.
Remember that if a line passes through two points (x₁, y₁) and (x₂,y₂) then the slope is:

In the graph, we can see that line B passes through (0, 0) and (1, 50), then the slope is:

Then the rate of change of B is 50.
The difference between the rates of change is:
diff = 50 - 35 = 15
