One end of a line segment has the coordinates (7, -18). If the other end has coordinates (-13, 10). what is the
midpoint

D

Step-by-step explanation:

To find the midpoint, take the averages of both the x and y coordinates of the 2 points.

First, add together the x-coodinates: 7 + -13 = -6. Then divide by 2: -6/2= -3. That means -3 will be the x coordinate of the midpoint.

Then, add together the y-coordinates: -18 + 10 = -8. Divide by 2: -8/2= -4.

-4 will be the y-coordinate of the midpoint.

So, the midpoint is (-3, -4) or D.
