An airport has two long-term parking lots. The cost to park, y, in each lot for x days is shown in the tables. Lot A
Days ParkedCost
1$16
2$20
3$24
4$28
Lot B

Days ParkedCost

1$6
2$12
3$18
4$24

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? Slove using y=mx+b
