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
• y = 3/10x + 25

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y +7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y+ 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)
