39 Kaitlyn runs a babysitting service. Her pay is always proportional to the number of
hours she works. When she works seven hours, she is paid $63. She tracks her recent hours worked and pay on a coordinate graph, with x representing the number of hours worked, and y representing her total pay based on x hours. On the graph, x would be the horizontal axis, and y would be the vertical axis.
Match the hours worked, x, with the corresponding total pay, y.
x, hours
y, total pay
