I am given dataset for period of a pendulum.

Length(cm) - 20 , 40 , 60 , 80 , 100

Period(1 cycle)- .89 , 1.26 , 1.55 , 1.79 , 2.00

Calculated

Frequency(1/Period) 1.12,0.79,0.65,0.56,0.50

Period^2 0.79,1.59,2.40,3.20,4.00

2. Relevant equations

I am suppose to create porportionality graphs, for data originally from the Length vs. Period data, the first graph provides a power relationship. As I go further to describe 1/Period, or known as the frequency I get an inverse relationship, now I need to make a third graph to create a linear relationship. My question is when modifying x-values to create porportionality graphs, do we only modify original data(x-values)? Since I have worked out Period^2 it does provide me with a linear relationship, now I just need to work on a porportionality statement. Would someone be able to confirm my answers. Also I need to relate the slope of the linear relationship to the frequency, I have no idea what that could be, but I am gonna keep thinking about it.

Thank You Very Much

3. The attempt at a solution

Would this be the porportionality statement?

Also I couldn't find the symbol for portionality, so thats the closest thing I could find.

LengthфPeriod^2
