Line A is represented by the equation given below:
MrMuchimi
To have infinitely many solutions they must describe the same line.  So any multiple or fraction of the reference line would indeed describe the same line, and thus "intersect" at each and every of an infinite number of points.

2(x+y=4)

2x+2y=8  (is the same line as x+y=4)
