## anonymous one year ago HELP REALLY NEEDED ASAP What is the coordinate of the midpoint of WQ -2 4 2 0 https://alle1333-allenschool-ccl.gradpoint.com/Resource/2159725,90A,0,0,0,0,0/Assets/testitemimages/geometry_a/tools_of_geometry/mc081-1.jpg

The formula for the midpoint between any pair $$a$$ and $$b$$ is this: $m=\frac{a+b}2$ It's the average! If you can't remember, there is a derivation. The whole length between $$a$$ and $$b$$ is $$b-a$$. The distance from $$a$$ to the midpoint is $$\frac12(b-a)$$. Then simplify! So, the midpoint is at $$a+\frac12(b-a)$$. $a+\frac12(b-a)=\\a+\frac12b - \frac12a=\\\frac12b+a-\frac12a=\\\frac12b-\frac12a=\\\frac12(b-a)$
