An airport has two long-term parking lots. The cost to park, y, in each lot for x days is shown in the tables.

A system of linear equations can be used to determine on which day the cost to park is the same for both lots. One of the equations in the
system is y=6x. What is the other equation in the system?

Answer:

  y = 4x +12

Step-by-step explanation:

The equation given matches the data for Lot B.

The cost in Lot A increases by $4 for each day, so that is the slope. Subtracting $4 from the cost for 1 day, we find the cost for 0 days would be $12. That is the y-intercept.

The equation for the cost in Lot A is ...

  y = 4x +12

_____

Both lots will charge $36 for a 6-day stay.
