Start with the given distance formula
d=sqrt%28%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2%29 where is the first point and is the second point

d=sqrt%28%283--2%29%5E2%2B%281--2%29%5E2%29 Plug in x%5B1%5D=3, x%5B2%5D=-2, y%5B1%5D=1, y%5B2%5D=-2

d=sqrt%28%285%29%5E2%2B%283%29%5E2%29 Evaluate 3--2 to get 5. Evaluate 1--2 to get 3.

d=sqrt%2825%2B9%29 Square each value

d=sqrt%2834%29 Add

So the distance approximates to

d=5.8309518948453

which rounds to
5.83

So the distance between (3,1) and (-2,-2) is approximately 5.83 units
