Step-by-step explanation:
In the question we need to find the distance between two points 5,6 and 0,-6 given.
Distance between two points can be found using the formula:

Putting the given points in the formula we get,
x₂ = 0, x₁ = 5, y₂= -6, y₁= 6

So, the distance between two points is √169 or 13.
