Question

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

Answer 1

midoint formula

the midoin between (x1,y1) and (x2,y2) is

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

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

(11,-22)=
`( (17+x2)/(2), (-19+y2)/(2))`

therfor
11=
`(17+x2)/(2)`
-22=
`(-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)
