Distance formula in R%5E2: d=sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29
Choice of which point is first does not matter, but you must be consistent.
Choose: x%5B2%5D=-6
x%5B1%5D=10
y%5B2%5D=y%5B1%5D=0
Then,
d=sqrt%28%28-6-10%29%5E2%2B%280-0%29%5E2%29
=sqrt%28%28-16%29%5E2%29
=16
