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