A line in the plane can be specified in various ways:

By giving a point (x,y) and a slope m (You DON'T NEED the Point Class)

by giving two Points (x1,y1), (x2,y2) (You DON'T NEED the Point class.)

as an equation in slope intercept form y = mx+b

as an equation x=a if the line is vertical

Implement a class Line with four constructors, corresponding to the four cases above. Implement methods:

boolean intersects (Line other)

boolean equals(Line other)

boolean isParallel(Line other).

there must be two classes
