Question

Point S is the midpoint of RT the coordinates of point R and point T are listed below R(-11,-12) T(-7,-4) what are the coordinates of point S

Answer 1

S (- 9, - 8 )

Explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

(
`(x_(1)+x_(2) )/(2)` ,
`(y_(1)+y_(2) )/(2)` )

here the endpoints are R (- 11, - 12 ) and T (- 7, - 4 ) , then

midpoint = (
`(-11-7)/(2)` ,
`(-12-4)/(2)` ) = (
`(-18)/(2)` ,
`(-16)/(2)` ) = (- 9, - 8 )
