Answer:
Part A: two lines, one line will be across $72 all the way. the second line will be a slope.
part b: 5 or less
Step-by-step explanation:
part A: time is x in the equation y=12x and y is the cost. so, plug in the x values and see what y values are. then plot the points and then draw a straight line.
part b: the rider charges $72 dollars for the whole day. if you wanted a bike from bikerama for 6 hours, it would be the same price. so, go for less hours and the price will be better
