Rate of change for Function A is: 35
Rate of change for Function B is: 50
Difference is: 15.
What is the Range of a Linear Function?
Rate of change = change in y / change in x.
The graph for function B is a proportional graph, therefore, rate of change = y/x.
Using a point on the line, (1, 50), rate of change for function B = 50/1 = 50.
Function A is given as y = 35x. Rate of change, is 35.
The difference = 50 - 35 = 15.
