Not sure what those two numbers represent without any diagram, but would it be helpful to tackle the problem as Trigonometry?
For example, SOH CAH TOA!
Tangent = Opposite / Adjacent (but you will need an angle)

or

Tangent = Hypotenuse of a triangle.
So, Tangent = squareroot( (9^2) - (-7)^2 ) = 4root2 (which is about 5.7 to 1 decimal place)

(if you google image Tangent, you will know what I mean)
