Do you know how to find the average of two numbers?

@RONNCC understanding a simple formula as midpoint - will help. some people are visual and others are analytical.

You add the two numbers together and divide by 2. That gives you the number in the middle. Do you understand that?

Well then, think of the midpoint as the average. You average the x values and average the y values and that gives you the point in the middle which is the midpoint.

So for (-2,1) and (-3,2) just find the average of -2 and -3. Then find the average of 1 and 2.
