Solving Systems of Equations - visually

Which statement DOES NOT describe a solution to a system of linear equations?

• The point where both lines intersect.

• The point where the y-axis and x-axis meet.

• An ordered pair that makes a true statement for both equations.

• An x-value and a y-value can be substituted into each linear equation to make a true statement.

• (0,-1.5)

• (1, -3)

• (5,0)

• (0,0)
