Create a system of linear equations

Question

Miles plans on leasing a new car and has been researching options from different dealerships. For the particular model he wants, Miles compiled the information from two dealerships in the table below.

Dealership Down Payment Monthly Lease Rate
Cool Cars      $1,999                          $179
Awesome Autos   $0                          $249

Create a system of linear equations that describe the total amount, y, paid towards the lease after x months. Write the slope-intercept form of the equation for Cool Cars followed by the slope-intercept form of the equation for Awesome Autos. Do not include dollar signs in the equations.

Answer 1

Let x = the monthly lease rate

Cool Cars: y = 179x + 1999

Awesome Autos: y = 249x
