Math Problem Statement

Find the midpoint of the segment with the following endpoints.

left parenthesis, 2, comma, 10, right parenthesis, and , left parenthesis, minus, 8, comma, 7, right parenthesis

(2,10) and (−8,7)

Solution

To find the midpoint of the segment with endpoints (2,10)(2, 10) and (8,7)(-8, 7), we 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)

Given:

  • x1=2x_1 = 2, y1=10y_1 = 10
  • x2=8x_2 = -8, y2=7y_2 = 7

Substitute these values into the formula:

Midpoint=(2+(8)2,10+72)\text{Midpoint} = \left( \frac{2 + (-8)}{2}, \frac{10 + 7}{2} \right)

Simplify each part:

Midpoint=(62,172)\text{Midpoint} = \left( \frac{-6}{2}, \frac{17}{2} \right)

Midpoint=(3,172)\text{Midpoint} = \left( -3, \frac{17}{2} \right)

Thus, the midpoint of the segment is (3,172)\left(-3, \frac{17}{2}\right).
