Question

What is the distance between the set of points (5,9) and (-7,-7)

Answer 1

The answer is

20 units

Explanation:

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

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5,9) and (-7,-7)

The distance between them is

`d = \sqrt{ ({5 + 7})^(2) + ( {9 + 7})^(2) } \\ = \sqrt{ {12}^(2) + {16}^(2) } \\ = √(144 + 256) \\ = √(400)`

We have the final answer as

20 units
