# What is the distance between (-1,101) and (2,-110)?

Jan 27, 2016

$\sqrt{44530} = 221.021$

#### Explanation:

So the distance formula is:

d=sqrt((y2-y1)^2+(x2-x1)^2

By plugging in the $x$ and $y$ values, you should get this:

d=sqrt((-110-101)^2+(2+1)^2

Solve.
First, work in the parenthesis.
$\sqrt{{\left(- 211\right)}^{2} + {\left(3\right)}^{2}}$
Then, do the rest.
$\sqrt{44521 + 9}$
$\sqrt{44530} = 221.021$
