Solving Linear System by Graphing

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

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

• TRUE
• FALSE
