Question

Find the distance between the pair of points with the given coordinates$\left(1,-14\right)\text{and}\left(-6,10\right)$.

Short answer

The distance between the given pair of points is$25\text{units}$.

Step-by-step solution

Step 1. Write down the given information.

The given pair of points have coordinates $\left(1,-14\right)\text{and}\left(-6,10\right)$.

Step 2. Concept used.

If a line segment has end-points at $\left(x_1,y_1\right)\text{and}\left(x_2,y_2\right)$ then the distance$\left(d\right)$ between these points is given as:

$\left|d\right|=\sqrt{{\left(x_2-x_1\right)}^2+{\left(y_2-y_1\right)}^2}\mathrm{....}\left(1\right)$

Step 3. Calculation.

The distance $\left(d\right)$between the pair of points with given coordinates $\left(1,-14\right)\text{and}\left(-6,10\right)$ is evaluated using the formula (1) stated above.

$\begin{array}{c}\left|d\right|=\sqrt{{\left(x_2-x_1\right)}^2+{\left(y_2-y_1\right)}^2}\\ =\sqrt{{\left(-6-1\right)}^2+{\left(10+14\right)}^2}\\ =\sqrt{{\left(-7\right)}^2+{\left(24\right)}^2}\\ =25\text{units}\end{array}$

Step 4. Conclusion.

The distance between the given pair of points is $25\text{units}$.
