We can compare the slopes and y-intercepts of two linear equations that express distance (in meters) as a function of time (in seconds), i. e. Michaels equation: d = 10t
Your equation: d = 7t + 100

Use the two equations to help you

a. In the 400-meter race, Michael caught up with you and moved on to win the race. Set up and solve an equation that will give the exact time when Michael ran past you on his way to the finish line.

(Note: I attached an image that I also need help with the graphing)
