Math Problem Statement

Find the midpoint of the segment with the following endpoints. left parenthesis, minus, 9, comma, minus, 10, right parenthesis, and , left parenthesis, 0, comma, minus, 7, right parenthesis (−9,−10) and (0,−7)

Solution

To find the midpoint of a line segment with endpoints (9,10)(-9, -10) and (0,7)(0, -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)

Substitute the given coordinates:

  • x1=9x_1 = -9, x2=0x_2 = 0
  • y1=10y_1 = -10, y2=7y_2 = -7

Now calculate each part:

x1+x22=9+02=92=4.5\frac{x_1 + x_2}{2} = \frac{-9 + 0}{2} = \frac{-9}{2} = -4.5

y1+y22=10+(7)2=172=8.5\frac{y_1 + y_2}{2} = \frac{-10 + (-7)}{2} = \frac{-17}{2} = -8.5

Thus, the midpoint is:

(4.5,8.5)\boxed{(-4.5, -8.5)}
