Answer: \sqrt{145}

Step-by-step explanation:

1. use the distance formula!

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

2. then using the distance formula with (2, 7) and (-6, -2) you get...

distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}

distance= \sqrt{8^2 +9^2}

distance=  \sqrt{64 +81}

distance= \sqrt{145}

\sqrt{145} is the simplest radical form
