Question

A(-1,9) and B(-3,5) ​

Answer 1

Explanation:

(-1 -3)/2 = -4/2 = -2

(9 + 5)/2 = 14/2 = 7

(-2, 7)

Option 2

Answer 2

`\textsf{Hey there!}`

`\mathsf{A (-1,9) \& \ B (-3,5)}`

`\mathsf{Formula: \ (x_1+x_2)/(2), (y_1+y_2)/(2)}`

`\mathsf{x_1 = -1}`

`\mathsf{x_2 = -3}`

`\mathsf{y_1 = 9}`

`\mathsf{y_2 = 5}`

`\mathsf{Equation: ((-1 + -3)/(2), (9 + 5)/(2))}`

`\mathsf{x \rightarrow -1 + -3 = -1 - 3 = -4}`

`\mathsf{y\rightarrow 9 + 5 = 14}`

`\mathsf{New\ equation: ((-4)/(2)),((14)/(2))}`

`\mathsf{x = (-4)/(2) =-2}`

`\mathsf{y = (14)/(2) = 7}`

`}\boxed{\mathsf{Thus, your\ answer\ is: \boxed{\mathsf {\bf{B.) M(-2,7)}}}}}\checkmark`
