Hi,

You want to use the distance formula. What exactly is the distance formula? It is used to find the units between two points. \[d = \sqrt{(x _{2} - x _{1}})^2 + (y _{2} - y _{1})^2\]

In here, we have the points: [(3, 18), (12, 3)]

Where:
x2 = 12
x1 = 3
y2 = 3
y1 = 18.

Plug these into the Distance Formula and solve.

Very nicely done. Note that the square root extends all the way over to include the y values.
