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

let the other end point be V(x, y)

the midpoint formula is basically add the 2 values then divide the answer by 2

so you have the answer....

so

for x: 5 = (3 + x)/2 solve for x


for y: -11 = (5 + y)/2 solve for y

the answers will be the ordered pair V

Answer 2

Okay, still don't know how to do that

Answer 3

Answer 4

well for each if you multiply both sides of the equation by 2

5*2 = (3 + x)/2*2

which means you get

10 = 3 + x

solve for y

same process for y

Answer 5

oops should read solve for x...

same process for finding y
