Chapter P.2, Problem 24E

Solution

The midpoint of the line with the given end points.

  $-11$

Given information:

Given points are $-5,\text{ and }-17$ .

Formula used:

The midpoint of a line segment with the end points $x_1,\text{ and }{x}_2$ , is given by:

  $\frac{x_2+x_1}{2}$

Calculation:

To calculate midpoint of the line with the given end points, use the formula for the midpoint of line segment with endpoints $x_1,\text{ and }{x}_2$ that is

  $\frac{x_2+x_1}{2}$

Here, points are $-5,\text{ and }-17$ , thus the midpoint is calculated as:

  $\begin{array}{c}\frac{-17+\left(-5\right)}{2}=\frac{-17-5}{2}\\ =\frac{-22}{2}\\ =-11\end{array}$

Thus, the midpoint of the line segment with given end points is $-11$ .
