Question

Find the coordinates

Answer 1

C (50, - 40 )

Explanation:

C is the midpoint of AB

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

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

here (x₁, y₁ ) = A (0, - 80 ) and (x₂, y₂ ) = B (100, 0 ) , then

C = (
`(0+100)/(2)` ,
`(-80+0)/(2)` ) = (
`(100)/(2)` ,
`(-80)/(2)` ) = (50, - 40 )
