If both those equations are equal to y, then that means by the transitive property, they are equal to each other. We set them equal to each other and solve for x. 4x - 28 = 1.5x - 18. Subtract 1.5x from both sides to get 2.5x = 10 and x = 4. Now sub that value in for x into one of the original equations to find y: y=4(4)-28 and y = 16 - 28 so y = -12. Your solution to that system is (4, -12), B

The format is y = mx + b
where y would be your C
x would be your M
m would be the price per mile (2.20)
and b would be your initial fee (2.75)

put this together in that format and we get
C = 2.20M + 2.75
