Question 12312: I'm stuck. I know how to do parts of the basic equations given to me, but the more complicated ones are giving me trouble. Here's my problem: I have to find the length and midpoint of (a,0) and %28%28a%2Bb%29%2F2%29,0

You can put this solution on YOUR website!
You are given 2 points.
Length is simply the distance between the 2 points
This can be found by D^2 = (X2-X1)^2 + (Y2-Y1)^2
Mid point is given by (X1+X2)/2,(Y1+Y2)/2
Can you solve this?
