What is the distance between the points (-5, -2) and (3, 13)? if necessary, round your answer to two decimal places?

In order to find the distance between the two points we utilize the Pythagorean Theorem,: 
Distance = Square Root ( (X difference)^2 + (Y difference)^2 )
So we have
Square Root (-5 -3)^2 + (-2 -13)^2 =
Square Root -8^2 + -15^2 =
Square Root (64 + 225)
=17
