Draw a dotted line to represent Maggie's race.
The equation of a line is y = mx + b (m is the slope, b is the y intercept.)
Where should you start the line if the runner hasn't started running yet?
What is the slope of the line you drew? Think about this when you draw the line. Remember, slope is rise over run so if you start on (0,0) count how far up then how far over you go to the next point. That number is m in the equation. The b is 0 since you started where y = 0
