Lesson Systems of Equations by Graphing

The solution to a system of equations is any ordered pair that makes both equations true. 

• TRUE
• FALSE

How can you tell if a point is a solution to a system?

• It makes the first equation true.
• The (x,y) coordinates satisfy both equations
• It makes logical sense
• It makes neither equation negative

^{What is the solution?}

• (1, 2)
• (1, -1)

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

What is the solution?

• (2, 2)
• (3, 2)
• (3, 4)
• (2, 3)
