Imagine that you are looking to rent a car that costs $15 a day, and you will be charged an additional 25 cents for every mile you drive it during the day. The following formula can be used to calculate the cost for driving the car for a day: C = 0.25m + 15 If you were to graph this equation on an xy-plane (m or mileage would be horizontal "x" value, and C or Cost would be the vertical "y" value), explain how you would interpret one of the following:
x-intercept
y-intercept
slope
an ordered pair
y = 0
0= .25x + 15
-15 = .25x
x = -60
x =0
y= .25(0) + 15
y = 15
Slope is .25
(-60,0),(0,15)
