The x-coordinate of M is halfway between the x-coordinates of C and D. That is the average value: (5+17)/2 = 11
Same for y: (9+29)/2 = 19
So, M = (11,19)
MC = √((11-5)^2 + (19-9)^2) = √(6^2+10^2) = √136
MD = √((17-11)^2+(29-19)^2) = √(6^2+10^2) = √136
I'm confused on how to do this. algebra M(X,Y) is midpoint of CD with endpoints C(5,9) and D(17,29).
Find the values of X and Y.
Show the MC = MD.
