Yes, it is a linear equation.
use 
to get 
then use
and 
also, 
to get 
then again use the first identity In both pairs, i.e.

to get 
multiply and divide by 4 to get the RHS.
because, 
squaring both sides, 
We are given that Jerry had his cruise control set at 60mi/h for 4 hours.
The rate of change is the second name of slope.
We are given rate of 60 miles per hour.
Thereofore, slope would be just 60.
And because it's keep 60 miles per hour for next 4 hours that is constant for next four hours.
Therefore it would stay positive.
So, we can say
1. Slope = 60
2. Positive.
The value of P Is 3!! Your welcome:))
