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

• It makes the first equation true.

• The (x,y) coordinates satisfy both equations

• It makes logical sense

• It makes neither equation negative

• The ordered pair (x, y) is a point on both lines

Does this system of equations have a solution? Explain your reasoning.
