How many miles apart are the library and the school

9 miles apart

Step-by-step 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.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
