Answer:
See below.
Step-by-step explanation:
Part A:
The two lines have the same slope and different y-intercepts. The graphs of the two equations are parallel lines, so there is no solution.
Part B:
The two lines are really the same line with the same slope and y-intercept. Therefore every point on the line is a solution. There is an infinite number of solutions.
Part C.
The two lines have different slopes, so they intersect at a single point. Therefore, there is one solution.
