Do you want to find the distance between these points?

Start with the given distance formula
where

is the first point

and

is the second point

Plug in , , ,

Evaluate to get -3. Evaluate to get -9.

Square each value

Add

Simplify the square root (note: If you need help with simplifying the square root, check out this solver)

So the distance approximates to

which rounds to
9.49

So the distance between (2,-5) and (5,4) is approximately 9.49 units
