Question

Find the distance between the points (1,8) and (-3,8)

Answer 1

4 units apart from both distances

Answer 2

Answer:

4 units

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} }$

From the question we have

$d = \sqrt{ {(1 - - 3)}^{2} + ({8 - 8})^{2} } \\ = \sqrt{ ({1 + 3})^{2} } \\ = \sqrt{ {4}^{2} } \: \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{16} \: \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

4 units
