Answer:
Use the distance, magnitude, norm, whatever formula.
You do this by using pythagorean and plugging in your values.
(6 - 0, -2 - 6) --> We subtract the individual x and y values from the two in order to find the line between the two.
Doing so will get you:
(6, -8)
sqrt(6^2 + (-8^2))
Now take the square and square root of them,
this gets you 10.
The distance is 10.
