Graphical Method for Inverse Proportional Relationship | AVS and 1/Mtot

[heathphysics]

hi there i am new to this , and might be posting at the wrong place, this is the first time I've posted.i really need somehelp with this guys.
does any1 know how to answer this

"Suggest a graphical method to determine the mathematical relationship between two quantities which are inversely proportional to each other.".
