Midpoint is the exact spot between two points. You bisect (divide into two equal halves) a given line segment. This middle point is called the "midpoint". The formula for midpoint is simple it's (x1 +x2)/2 , (y1+y2)/2 =xm,ym

Point B is (-2,5) Point C is (6,-3)
We want to find the point halfway between them.

First we add both x values, then divide the sum by two to find the X Midpoint Value. (-2+6)/2 simplifies to (4)/2 which equals 2.

The new midpoint coordinate is (2, y) Now, we need to repeat the same steps for the y value.

Add both y values, then divide the sum by two to get the Y Midpoint Value. (5+(-3))/2 simplifies to (2)/2 which equals 1.


The new midpoint coordinate is (2, 1).

The answer is D (2,1)
