The rate of change means that the designer hourly charge is $55 per hour

Linear equation

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total cost of hiring the designer after x hours.

From the table, using the point (0, 125) and (15, 950):

  • [tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{950-125}{15-0}=55[/tex]

The rate of change means that the designer hourly charge is $55 per hour
