Relating y=mx+c and T^2=kd^3+4pi^2l/g

Homework Statement

Can someone please tell me how these two equations are related

The first is just the generic equation for a line in 2-D space. The second does not seem to be related to it at all. Are we supposed to just guess where you got these and why you want to compare them? That is, should we just guess what the context of your question is?

Hi NM. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif

I don't recognize the kd^3 term. Where did this equation for T^2 come from?

Well we got a pendulum lab to perform and had to relate the period T^2 to the distance of a yielding support d^3. That equation was provided to us to use to determine the values of k and g in the equation, where k was a constant and g was acceleration of free fall
