The number of solutions of two linear equations is given by their points of intersection.
If the two lines coincide, the number of solutions is infinite.
If the two lines are not parallel then the number of solutions is 1
If the two lines are parallel and do not coincide then the number of solutions is 0.
In this case, the two linear equation have the same slope but different y-intercept.
Therefore, the graphs of the two equations are parallel and do not coincide.
Therefore, the number of solutions is 0
