I can do the solution, I do not understand the theory!
Here it is:
Using a pendulum to determine g using T = 2π√(l/g)
(that little n looking thing is pi)
(given l and T)
So, then we get
T^2 = (4π^2/g) x l
This is where I get lost.
Supposedly, I am to make the equation T^2 = kl (where k is the group of constants)
Then, I am to compare this formula with the general equation for a straight line y=kx.
Thus, k = m (of a graph, where vertical T^2 and horizontal l is the axis)
Why/how does k = m ?
k being (4π^2/g)
and m being the gradient of my graph?

Thank you!
