a.) Initial cost of renting the car is $100
b.) rate of change is slope, that is :
c.) Cost = C and distance = d
the equation will be :
4/5 of 60 = 48. 4/5 = .80 Multiply .80 by 60 =48
X 0 y was 30
at x 12 y is about 55
12-0 = 12
55-30 = 25
25/12 = 2.08 inches per year average
so answer should be D
Y=1/4-2 is the correct answer. you go up one and over four. the y-intercept is -2
