How do you find the endpoint of a line segment?

Answer 1

Use the midpoint formula.

( x1 + x2 / 2 , y1 + y2 / 2 )

For example, if you were given segment QR with midpoint M(-1, -1) and endpoint Q(-8, 10):

(-1, -1) = ( x1 + -8 / 2 , y1 + 3 / 2)

X COORDINATE

-------------------

-1 = x1 + -8 / 2

-2 = x1 - 8

6 = x

Y COORDINATE

-------------------

-1 = y1 + 10 / 2

-2 = y1 + 10

-12 = y
