Use the distance formula: d+=+sqrt%28%28x%5B1%5D+-+x%5B2%5D%29%5E2+%2B+%28y%5B1%5D+-+y%5B2%5D%29%5E2%29. Just plug in the coordinate values from your two points and do the arithmetic. Watch your signs carefully.

D= the square root of the difference of the x coordinates squared + the difference of the y coordinates squared
:
D=sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29
:
so
:
D=sqrt%28%28-5-%28-1%29%29%5E2%2B%28-7-%28-4%29%29%5E2%29
:
D=sqrt%28%28-4%29%5E2%2B%28-3%29%5E2%29
:
D=sqrt%2825%29
:
highlight%28D=5%29
