Katy babysat to make some money, but Katy has not worked any hours so (x=0), she has not earned any wages so (0,0) would be one coordinate. Katy earns 10 dollars an hour. She then worked 3 hours, so she now has $30.00, so (3,30)is another point. Katy worked 15 hours earning making $150.00, so then (15,150). X=hours she babysat and y is the money earned. Where would her slope be?

Answer 1

every time she works one more hour, how much more money does she get? That is the slope of the line.
