Question

Midpoint (11,-22) endpoint (17, -19) find the other endpoint

Answer 1

Midoint formula

the midoin between (x1,y1) and (x2,y2) is
$( \frac{x1+x2}{2}, \frac{y1+y2}{2})$

midpont=11,-22
endoint is 17,-19

(11,-22)=$( \frac{17+x2}{2}, \frac{-19+y2}{2})$

therfor
11=$\frac{17+x2}{2}$
-22=$\frac{-19+y2}{2}$
solve each
times 2 to both sides of both euations

22=17+x2
-44=-19+y2

minus 17 both sides for first
add 19 both sides for second

5=x2
-25=y2

the other endpoint is (5,-25)
