Question

Find the distance between the points (-1,-2) and (5,2). Simplified radical form.

Answer 1

Answer:

2$\sqrt{13}$

Step-by-step explanation:

Using the distance formula,

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

We just need to plug in the numbers.

So $\sqrt{(-1-5)^2+(-2-2)^2}$

Then we simplify it to

$\sqrt{(-6)^2+(-4)^2} , to \sqrt{36+16}$

Finally, we get

$\sqrt{52}$, which is $2\sqrt{13}$ when simplified.
