FIRST YOU NEED TO FIND THE DISTANCE BETWEEN THE X & Y VALUES THUS:
5+1=6 IS THE X DISTANCE.
7-3=4 IS THE Y DISTANCE.
KNOWING THAT YOU HAVE A RIGHT TRIANGLE & THE DISTANCE IS THE HYPOTENUSE OF THIS TRIANGLE WE USE THE PYTHAGOREAN FORMULA A^2+B^2=C^2
6^2+4^2=C^2
36+16=C^2
52=C^2
C=SQRT52
C=7.2 IS THE DISTANCE BETWEEN THESE 2 POINTS.

The distance formula is
D%5E2=%28x%5B1%5D-x%5B2%5D%29%5E2%2B%28y%5B1%5D-y%5B2%5D%29%5E2
D%5E2=%28-1-5%29%5E2%2B%283-7%29%5E2
D%5E2=36%2B16
D%5E2=52
D=7.2
