Math Problem Statement

Find the midpoint of the segment with the following endpoints. left parenthesis, minus, 10, comma, 8, right parenthesis, and , left parenthesis, minus, 4, comma, minus, 2, right parenthesis (−10,8) and (−4,−2)

Solution

To find the midpoint of a line segment with endpoints (10,8)(-10, 8) and (4,2)(-4, -2), you can use the midpoint formula:

Midpoint=(x1+x22,y1+y22)\text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)

Here, (x1,y1)(x_1, y_1) is (10,8)(-10, 8) and (x2,y2)(x_2, y_2) is (4,2)(-4, -2).

Substituting the values:

Midpoint=(10+(4)2,8+(2)2)\text{Midpoint} = \left( \frac{-10 + (-4)}{2}, \frac{8 + (-2)}{2} \right)

Simplify the expressions:

Midpoint=(142,62)\text{Midpoint} = \left( \frac{-14}{2}, \frac{6}{2} \right)

Midpoint=(7,3)\text{Midpoint} = (-7, 3)

So, the midpoint of the segment is (7,3)(-7, 3).
