Anna wants to take fitness classes. She compares two gyms to determine which would be the best deal for her. Fit Fast charges a set fee per class. Stepping Up charges a monthly fee, plus an additional fee per class. What is the system of equations representing these costs?

y = 5.5x and y = 7.5x + 10
y = 7.5x and y = 5.5x
y = 7.5x and y = 5.5x + 10
y = 7.5x + 10 and y = 5.5x + 10

Plug in the Y and X values for each line on each problem.

Ex) If I had (4, 32) and y = 5.5x on the first problem, then I would put in 32 = 5.5(4) and see if I get 32=32. If I don't get 32=32, then it isn't true and you can try to test it with the next one on the problem as that point may not apply to the equation.
