A car starts from point P at time t=0 and travels at 45 mph.

A)write an expression d(t) for the distance the car travels from p. (would it just be y=45x??)
B)What is the slope of the graph? what does it have to do with the Car?
D)Create a scenario in which t could have negative values
E)create a scenario in which the y-intercept of y-d(t) could be 30.

    a. correct, but I would do it this way:
    d(t)=45mph* t where t is in hours.

    b. slope is 45mph
