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
