what exactly is the midpoint formula?? I am taking an oline summer school course in geometery and every website I go to tells me something different

for any two points (a,b) and (c,d)

the midpoint is ((a+c)/2,(b+d)/2)

in words, add up the x's and divide by 2, then add up the y's and divide by 2

in essence your are "averaging" the x's and y's

ok, the one my teacher sent me was (x1+x2)/2,(y1+y2)/2

Right!

Saying the same thing using different letters, that's all.
