# Find the distance between the pair of points with the given coordinates $\left(0.23,0.4\right)\text{and}\left(0.68,-0.2\right)$.

The distance between the given pair of points is $\frac{3}{4}\text{units}$.

See the step by step solution

## Step 1. Write down the given information.

The given pair of points have coordinates$\left(0.23,0.4\right)\text{and}\left(0.68,-0.2\right)$.

## 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:

$\left|d\right|=\sqrt{{\left({x}_{2}-{x}_{1}\right)}^{2}+{\left({y}_{2}-{y}_{1}\right)}^{2}}....\left(1\right)$

## Step 3. Calculation.

The distance $\left(d\right)$ between the pair of points with given coordinates $\left(0.23,0.4\right)\text{and}\left(0.68,-0.2\right)$ is evaluated using the formula (1) stated above.

$\begin{array}{c}\left|d\right|=\sqrt{{\left({x}_{2}-{x}_{1}\right)}^{2}+{\left({y}_{2}-{y}_{1}\right)}^{2}}\\ =\sqrt{{\left(0.68-0.23\right)}^{2}+{\left(-0.2-0.4\right)}^{2}}\\ =\frac{3}{4}\text{units}\end{array}$

## Step 4. Conclusion.

The distance between the given pair of points is $\frac{3}{4}\text{units}$.
