Which ordered pair is a solution of the system of linear equations whose graph is shown?

• (0,2)
• (3/2, 0)
• (5,4)
• (4,5)

When a system of equations has infinite solutions that means...

• the lines have the same slope and y-intercept
• the lines are parallel
• the lines have different slopes.
• the lines have different y-intercepts.
