I could give you a long spiel about the "distance" formula, but here's a nice little trick to use when one of the points has a coordinate value of "0." Let's make, both of them "0."
Subtract 6 from the " y values" in both sets of points.
This gives us (0,0) and (5, -10)
Now, square both values in the second point and add them together...so we have
(5)2 + (-10)2 = 25 + 100 = 125
Now, take the square root of this
√(125) = √[(25)(5)] = √(25) * √(5) = 5√5... and there you go !!!
The "distance" formula would return the same thing, but here, we didn't have to remember any "formula."
