Given the function d(h)=50+45 represents the distance a family traveled, in miles, h hours after they stopped for lunch. The value 45 represents the speed they are traveling in miles per hour. So if the function will be graph, the 45 represents the slope of the line.

 

After lunch, the family traveled at a speed of 45 mph.
