The y-intercept of a graph gives important information about the function that the graph represents. In the graphs shown here, the y-intercept is the amount of money you earn as base pay each week.

To Do:
1. Read the descriptions on the right of what the different lines represent.
2. Experiment with the graph. Drag the slider to change the y-intercept of the green line to find what you think would be a good base pay.]]> Blue Line: Graph of weekly salary at ATSF where you get a base pay of $300/week and $.50 per pair of shoes you sell. (y = 0.5x + 300)

Red Line: Graph of weekly salary at As The Shoe Fits where you simply earn $5 per pair of shoes you sell. (y = 5x)

Green Line: Graph of weekly salary where you earn $2 per pair of shoes sold plus a base pay that you choose. (y = 2x + base salary) ]]>
