• Car A

• Car B

Kiran and Clare like to race each other home from school. They run at the same speed, but Kiran's house is slightly closer to school than Clare's house. On a graph, their distance from their homes in meters is a function of the time from when they begin the race in seconds. As you read the graphs left to right, would the lines go up or down?

What is different about the lines representing Kiran's run and Clare's run?

What is the same about the lines representing Kiran's run and Clare's run?

Write an equation for each line.
