The dots on the graph above show his distance from the school at various times , starting at home at t=0 (black dot). After 5 minutes Joe is 3.2 kilometers from the school (second black dot). The data show that his speed is almost constant , and his distance from the school can be approximated by a straight line . The graph of the function that models Joe's distance from school as a function of time , in minutes , is shown as a solid line. Which of the following equations best represents this function ?
