Respuesta :

Answer:

(0.5,-1.5)

Step-by-step explanation:

this is the numbers i got when I put it in...

m=([tex]{-\frac{1+0}{2} , \frac{-5+2}{2}[/tex])

(0.5,-1.5)

Answer:

S = (2, - 12 )

Step-by-step explanation:

Using the midpoint formula

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Equate each of the coordinates of the midpoint

let S = (x, y ), then

(x₁, y₁ ) = T(0, 2) and (x₂, y₂ ) = S(x, y ), then

 [tex]\frac{0+x}{2}[/tex] = 1 ( multiply both sides by 2 )

x = 2

[tex]\frac{y+2}{2}[/tex] = - 5 ( multiply both sides by 2 )

y + 2 = - 10 ( subtract 2 from both sides )

y = - 12

S = (2, - 12 )
