What is the distance between (-5, 5) and (1, -2)

Murrr4er [49]

Answer:

$\displaystyle d=\sqrt{85}\text{, or about 9.22 units}$

Step-by-step explanation:

We will use the distance formula to solve.

$\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}$

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

$\displaystyle d=\sqrt{(6)^2 +(-7)^2}$

$\displaystyle d=\sqrt{36+49}$

$\displaystyle d=\sqrt{85}\text{, or about 9.22 units}$
