# SHM, Determing Spring Constant from Period^2 vs. Mass

Help!

I'm trying to find the spring constant (k) of a spring using simple harmonic motion. I have a graph of Period^2 vs. Mass.

Knowing that T=2*$$\pi$$*$$\sqrt{m/k}$$

How would one find k from the slope of this graph?
My linear fit yields: y=5.237x+0.003
5.237 being my slope

HINT: Using what you know can you get an Equations for T^2 in terms of mass? If so, the slope of that equation is 5.237.
