Monica was taking a bus trip to see her aunt.  For her to ride 50 miles it cost her $40.  For her to ride 250 miles the bus trip would cost her $100.  Find the rate of change in dollars per mile.  Write an equation in slope-intercept form to model this situation.

• y = 3/10x + 40
• y = 2.5x + 25
• y = 3/10x + 30
