The equation of the rental rate in slope-intercept form(y = mx + b) that models the total cost of the rental over time is; C = $20t + $60.

The slope intercept form of a linear equation takes the form; y = mx + c.

In this scenario;

  • The one-time fee, $60 represents the y-intercept of the rental rate equation.

  • The daily charge, $20 represents the slope of the rental rate equation.

Ultimately, the rental rate equation is; C = $20t + $60
