What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid?

To find this, we need to find the hypotenuse of the triangle created. The base of the triangle is 3 units long. The height of the triangle is 2 units tall. So:
3^2 + 2^2 = c^2
9 + 4 = c^2
13 = c^2
The distance between the two points is √13
