Chapter 10: Q17. (page 661)

Find the distance between the points with the given coordinate.
$(- 3, 4), (- 2, - 3)$

Short Answer

Expert verified

The distance between the coordinates $(- 3, 4)$ and $(- 2, - 3)$ is $\sqrt{50}$ units.

Step by step solution

Step 1. State the concept of ‘Distance between two points in 2 dimensional plane’.

Let the two points in 2 dimensional plane be $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ .

The distance between the points is given as:

$d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} \dots (1)$

Where $d$ is the distance.

Step 2. Calculate the distance.

The two points which is given are $(- 3, 4)$ and $(- 2, - 3)$ .

Substitute $(- 3, 4)$ as $(x_{1}, y_{1})$ and $(- 2, - 3)$ as $(x_{2}, y_{2})$ in $(1)$ to calculate the distance.

$\begin{array}{l} d = \sqrt{{(x_{2} - x_{1})}^{2} + {(y_{2} - y_{1})}^{2}} \\ = \sqrt{{(- 2 - (- 3))}^{2} + {(- 3 - 4)}^{2}} \\ = \sqrt{{(- 2 + 3)}^{2} + {(- 7)}^{2}} \\ = \sqrt{{(1)}^{2} + {(- 7)}^{2}} \\ = \sqrt{1 + 49} \\ = \sqrt{50} \end{array}$

Step 3. State the conclusion.

Therefore, distance between the points $(- 3, 4)$ and $(- 2, - 3)$ is $\sqrt{50}$ units.
