Question

Find the distance between (-1, 4) and (1,-1).

Answer 1

Answer:

The answer is

$\sqrt{29} \: \: units$

Step-by-step explanation:

To find the distance between two points we use 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

(-1, 4) and (1,-1)

The distance between them is

$d = \sqrt{ ({ - 1 - 1})^{2} + ({4 + 1})^{2} } \\ d = \sqrt{ ({ - 2})^{2} + {5}^{2} } \\ d = \sqrt{4 + 25}$

We have the final answer as

$d = \sqrt{29} \: \: \: units$
