Current against slip relationship of induction machine??

Please could someone explain to me the relationship between the current and the slip value of an induction machine. I have plotted a graph and I am wondering how to interpret this?

Thankyou.

If you are writing about an induction motor then the slip is the difference between the stator and rotor magnetic field. The larger the slip the greater the current pull from the line. When the motor is working there is always slip and if the load is too great for the motor the slip causes a higher than designed current pull and this trips an overload.
