Need help with my exam review! Find the midpoint of segment AB that has endpoints at the coordinates (4, -8) and (5,2). I used the midpoint formula and got (-2, 3.5) but I'm not sure it's right...

Question

mertsj · Answer

Think of the midpoint as the average:  add the x values and divide by 2.   add the y values and divide by 2.  That will be the midpoint.

mertsj · Answer

4+5=9 and 9 divided by 2 is 4.5
-8+2 =-6 and -6 divided by 2 is -3
So the midpoint is (4.5,-3)

Is that easier then the midpoint formula?

Also the next question I have says coordinates (-3,12) and the origin. Is origin (0,0)?
