Midpoint (Mpt.)
posted by Xochitl at 1:02 p.m.
hi everyone! :) How are you? I'm here to help you with your math problems! (limited to the midpoint formula). Ok, so when using the midpoint formula it is very important to remember a few things:
*always keep the x1 with the y1 and the x2 with the y2
*your adding the x's and the y's so if you have a negative don't get confused (I use brackets becauase it keeps my mind focused and off of muffins! :P)
*don't add your x and y answers like you do in the distance formula, keep them seperated, remember your trying to get a point, so you should get two numbers
example;
formula for Mpt. = (x1+x2 , y1+y2) formula for distance = (the square root sign) (x2-x1) 2 + (y2-y1) 2

Don't forget that the formula for midpoint is an average of the to points so x1 + x2 must be divided by 2, and y1 +y2 must also be divided by 2.
