Solve by graphing. Label the axes and show where the solution is located on the graph.The cost of a car rental is $12 plus $0.25 for each mile the car is driven. The cost, c, in dollars of the rental is given by the linear equation c = 12 + 0.25m, where m is the number of miles driven. (a) Find the missing coordinate for the ordered pair  which corresponds to driving 34 miles. (b) In addition to the ordered pair from part (a), find at least two more ordered pairs and use these to graph the equation.
