A car starts from point P at time t= 0 and travels at 45 mph.
Write an expression d(t) for the distance the car travels from P.
Graph y = d(t)
What is the slope of the graph in (b)? What does it have to do with the car?
Create a scenario in which t could have negative values
Create a scenario in which the y-intercept of y= d(t) could be 30.
