The point that simultaneously satisfies both equations is:

• (4, 3)

• (3, 4)

• (-4, 3)

• No solution

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
