Marco is observing the system of equations below and believes it will have exactly one solution. Is he correct? Why or why not?

• No, the slopes are the same and the y-intercepts are different, so there would be infinite solutions to the system of equations.

• No, the slopes are the same and the y-intercepts are different, so there would be no solution to the system of equations.

• Yes, the slopes are the same so they will intersect and have one solution.

• Yes, the y-intercepts are different so they will intersect and have one solution.
