Answer:
9 miles apart
Explanation:
We can graph these two points on a graph.
When we graph it, we can see that since the y's are the same, the points create a straight horizontal line.
To find the difference, we can subtract the two values of x, or we can count the distance.
5-(-4)
5+4
9 miles
When we count the number of grids between the two points, we can also see that there are 9.
