Homework Help: math

Posted by Dawn on Thursday, February 3, 2011 at 6:44pm.

I am trying to find the coordinates of a point in a line. I have one end, and I have the midpoint. What formula should I use to find the one on the end?

The one end is (8,4) and the MIDPOINT is (14, 7). What would I do to find the opposite point?!
thanks!

(8,4) (14,7) (x, y)

x - 14 = 14 - 8
x = 20

y -7 = 7 - 4
y = 10

(20,10)
