  • Two functions, y = |x - 3| and 3x + 3y = 27, are graphed on the same set of axes. Which statement is true about the solution to the system of equations? (1) (3,0) is the solution to the system because it satisfies the equation y = |x - 3|. (2) (9,0) is the solution to the system because it satisfies the equation 3x + 3y = 27. (3) (6,3) is the solution to the system because it satisfies both equations. (4) (3,0), (9,0), and (6,3) are the solutions to the system of equations because they all satisfy at least one of the equations.
