Point B is at (3,1).
For which segment is B a midpoint?
O AC with endpoints at A(1,-1) and C(5,3)
O AD with endpoints at A(1,-1) and C(6,4)
O AC with endpoints at A(1,-1) and C(8,6)
AC with endpoints at A(1, -1) and C(7,5)

Respuesta :

Answer:

AC with end points A (1,-1) and C (5,3)

Step-by-step explanation:

mid point is calculated using the equation

[tex]( \frac{x1 + x2}{2}) .( \frac{y1 + y2}{2} )[/tex]

so from AC, with end points A (1,-1) and C (5,3). If we substitute the values back into the equation.

[tex]( \frac{1 + 5}{2} ).( \frac{ - 1 + 3}{2} )[/tex]

When we solve we get the same values for the midpoint
