What is the method of rotating a straight line about a point and compute the new equation of the rotated line ?

Say we have to rotate ax+by+c =0 through the angle Theta about the point P(x,y). And then find the Equation of the line after rotation.

So I found some similarities between arrays and set notation while learning about sets and sequences in precalc e.g. set notation: {a | cond } = { a1, a2, a3, a4, ..., an} given that n is the domain (or index) of the array, a subset of Natural numbers (or unsigned integer).
