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

  2. Hope it is right

What does it mean if a linear system has one solution?

• The lines intersect at one point
• The lines do not intersect
• The lines intersect at many points
