## Step by step guide to find the distance of two points

- Distance of two points A \((x_{1},y_{1})\) and B \((x_{2},y_{2})\)

\(\color{blue}{d=\sqrt{(x_2-x_1)^{2}+(y_{2}-y_{1}){^2}}}\)

### Finding Distance of Two Points – Example 1:

Find the distance of two points \((1,6) \ and \ (4,2)\).

**Solution:**

Use distance of two points formula: \(\color{blue}{d=\sqrt{(x_2-x_1)^{2}+(y_{2}-y_{1}){^2}}}\)

\((x_{1},y_{1})=(1,6)\) and \((x_{2},y_{2})=(4,2)\). Then: →

\(d=\sqrt{(4−1)^{2}+(2−6)^{2}}=\sqrt{(3)^{2}+(−4)^{2}}=\sqrt{9+16}=\sqrt{25}=5→d=5\)

### Finding Distance of Two Points – Example 2:

Find the distance of two points \((-1,5) \ and \ (-3,-6)\).

**Solution:**

Use distance of two points formula: \(\color{blue}{d=\sqrt{(x_2-x_1)^{2}+(y_{2}-y_{1}){^2}}}\)

\((x_{1},y_{1})=(-1,5)\) and \((x_{2},y_{2})=(-3,-6)\). Then: \(→\)

\(d=\sqrt{(-3−(-1))^{2}+(-6−(5))^{2}}=\sqrt{(-2)^{2}+(−11)^{2}}=\sqrt{4+121}=\sqrt{125}=5\sqrt{5}\) Then: \(d=5 \sqrt{5} \)

### Finding Distance of Two Points – Example 3:

Find the distance of two points \((0,8) \ and \ (-4,5)\).

**Solution:**

Use distance of two points formula: \(\color{blue}{d=\sqrt{(x_2-x_1)^{2}+(y_{2}-y_{1}){^2}}}\)

\( (x_{1},y_{1})=(0,8)\) and \((x_{2},y_{2})=(−4,5)\). Then: \(d=\sqrt{(x_{1}−x_{2})^2+(y_{1}−y_{2})^2}→\)

\(d=\sqrt{(0−(−4))^2+(8−5)^2}=\sqrt{(4)^2+(3)^2}=\sqrt{16+9}=\sqrt{25}=5→d=5\)

### Finding Distance of Two Points – Example 4:

Find the distance of two points \((4,2) \ and \ (-5,-10)\).

**Solution:**

Use distance of two points formula: \(\color{blue}{d=\sqrt{(x_2-x_1)^{2}+(y_{2}-y_{1}){^2}}}\)

\( (x_{1},y_{1})=(4,2)\) and \((x_{2},y_{2})=(−5,-10)\). Then: \(d=\sqrt{(x_{1}−x_{2})^2+(y_{1}−y_{2})^2}→\)

\(d=\sqrt{(4−(−5))^2+(2−(-10))^2}=\sqrt{(9)^2+(12)^2}=\sqrt{81+144}=\sqrt{225}=25→d=15\)
