What are the coordinates of the midpoint of the segment whose endpoints are A (-1, -2) and B (6, 12)

Klio2033 [76]

Answer:

Mid point = $(\frac{5}{2} ,5)$

Step-by-step explanation:

We are given the coordinates of the end points of a line segment AB and we are to find the coordinates of its mid point.

The coordinates of the end points are: A (-1, -2) and B (6, 12).

We know the formula of the mid point:

Mid point = $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

So putting in the given values to find the mid point of line segment AB:

Mid point = $(\frac{-1+6}{2} ,\frac{-2+12}{2} )$ = $(\frac{5}{2} ,5)$
