Question

Find the other endpoint of the line segment with the given endpoint and mid point.
Endpoint:(-1, 9), midpoint: (-9, -10)

Answer 1

what's the difference between the midpoint and endpoint in terms of x and y?

Answer 2

that is to say what is (Xmid-Xend) and (Ymid-Yend)

Answer 3

Diferrence in the mid x and y is -8???
and the difference in the end x and y is -1???

Answer 4

not between the x and y of the same point but the x's and y's
x end -x mid and y end - y mid

Answer 5

x's
mid x= -9 end x= -1
xmid-x end = -8

y's
mid y - end y

this will show you how far to extend the line to the other end point

Answer 6

ok
