Question

Find the coordinates of the midpoint of HX given that H(-1,3) and X(7,-1)

A.(3,1)
B.(0,4)
C.(-3,1)
D.(-4,0)

Answer 1

The midpoint of AB where
`A(x_A;\ y_A)` and
`B(x_B;\ y_B)`


`\left((x_A+x_B)/(2);\ (y_A+y_B)/(2)\right)`


`H(-1;\ 3);\ X(7;-1)`

The midpoint of HX:
`\left((-1+7)/(2);\ (3+(-1))/(2)\right)=\left((6)/(2);\ (2)/(2)\right)=(3;\ 1)`

Answer: A(3, 1)
