Question

The midpoint of line UV is (5,-11). The coordinates of one endpoint are U(3, 5). Find the coordinates of endpoint V.

Answer 1

wouldnt it be 7,27

Answer 2

do you have multiple choice
because that would help me more i do my math backwards lol dont ask i jus learned that way

Answer 3

finding midpoint is

p1+p2/2

(x1 +x2)/2
= midpoint x

and

(y1 +y2)/2
= midpoint y

we know midpoint is 5 for x and endpoint is 3 so

(3+x)/2=5 multiply both sides by 2
3+x=10 2's canceled
3-3+ x = 10 -3
x=7

do the same to figure out your y
