Equilibrium of Rigid bodies, Rigid body rotation equations of rotational motion ... Para-, dia- and ferromagnetic substances with examples. The effect of temperature on magnetic properties.

If an equation can be rearranged into the form \(y = mx + c\), then its graph will be a straight line. In the above: \(x + y = 3\) can be rearranged as \(y = 3 - x\) (which can be re-written as ...
