Answer: See attached.
Step-by-step explanation:
When we have a simple x = a equation, the line will be vertical since all y values of that function/equation are equal to a. In this case, that is 1.
Similar thing for a y = b equation. The line will be horizontal since all x values of that function/equation are equal to b. In this case, that is -5.
D(x)=62.5x+15 x is how far he goes when he travels 62.5 miles per hour. Since he is already 15 miles north of the city we add that in as our "starting" distance. On a graph, this would be the y-intercept and the speed would serve as the slope. This is given as a linear relationship.
