Answer:

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable

You can find the rate of change by using this formula:

$m=(y_2 - y_1)/x_2 -x_1$

That m would go into another formula known as slope-intercept form

The equation is

y = mx +b

m = rate of change (or) slope

b = y-int

The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
