Find the coordinate of the midpoint of the segment with the given endpoints.
negative 4 and 9

Explanation:

Step 1)

Add up the given values to get -4+9 = 5

note that -4+9 is the same as 9+(-4) = 9-4

Step 2) Divide the result from step 1 above by 2 to get

5/2 = 2.5

The general midpoint formula is

C = (A+B)/2

where A and B are the endpoint values and C is the midpoint of segment AB. Points A,B,C are all on the same number line.

In this case, A = -4 and B = 9, so,

C = (A+B)/2

C = (-4+9)/2

C = 5/2

C = 2.5

slope is 35 and 20 miles is the y-intercept.
