advice

i need help w/ this math problem:

Ed has a car needing repair. he has researched repari shops and found that Franks Body Shop charges a flat fee of $350 for any size job. manuels fix-it right shop cahrges a flat fee of $100 plus a rate of $50/hour. At what "repair time" would the two repari shops charge an equal amount? Who sould Ed employ if he know the repair will take 1 hour? who should he employ if the repairs will take 3 hours?

i have to define variables, write a system of equations and graph the system of equations, and solve the system of equations.
i got the following so far:

y=fee, x=cost
frank...... y=$350
Manuel..... y=50(x)+100

i dont know how to graph these or solve them. i know what i have is right cause i had my teacher check it. but now i'm stuck. Plez help. thank you so much!

Graphing isn't all that bad. I'm sure you've seen a graph before but if not, it's basically a grid line with two main parts. the x-axis (the center of the grid line going horizontal) and the y-axis (the center of the grid lines going vertical). So to graph these, you just find the value of each one when y=0, for the frank one, it will be a straight line at the value of 350 because there is no variable other than that. For Manuel you find different values of y when you substitute soemthing for x and those are points on the line. Then you just connect the dots.
