See the picture below for a way to construct a right triangle that makes that piece the longest side of the triangle your line segment.

With that setup, you can use they Pythagorean Theorem.

7^2 + 6^2 = c^2

And then solve that for c, keeping in mind c must be positive.

$\begin{aligned}49 + 36 &= c^2\\85 &= c^2\\\sqrt{85} &= c\end{aligned}$

If you want to use the distance formula, that is just the Pythagorean theorem solved for c:

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Applying that to your situation

$d = \sqrt{(5-(-2))^2+(-5-1)^2} = \sqrt{(7)^2+(-6)^2} = \sqrt{49+36} = \sqrt{85}$
