Question

how do you put T=2pi*root of M divide by K in the form of y=mx+c?

Answer 1

which are your variables and which are your constants?

Answer 2

\[T=2\pi \sqrt{\frac{ M }{ K }}\]

Technically, the T would be your y variable, and you wouldn't have x-intercept (c = 0).

Is k your spring constant? T for energy? You really need to define the terms, but hopefully this helps.
