Chapter 11: Q. 11.4 (page 1072)

Use the Distance Formula to find the distance between the points $(- 2, - 5)$ and $(- 14, - 10)$ .

Short Answer

Expert verified

The distance between the points is $13$ .

Step by step solution

Step 1. Definition

The distance between two points $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ is given by the distance formula as $d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}}$ .

Step 2. Substitute the values in the formula

We need to find the distance between the points $(- 2, - 5)$ and $(- 14, - 10)$ .

So in the distance formula substitute $- 2$ for $x_{1}$ , $- 5$ for $y_{1}$ , $- 14$ for $x_{2}$ , and $- 10$ for $y_{2}$ and simplify.

$d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} d = \sqrt{(- 14 - {(- 2))}^{2} + (- 10 - {(- 5))}^{2}} d = \sqrt{{(- 12)}^{2} + {(- 5)}^{2}} d = \sqrt{144 + 25} d = \sqrt{165} d = 13$
