Answers vary

300

Is the ordered pair a solution for the linear system?

Why or why not?

(8,5)

 5x-4y=20

3y=2x+1

No because it is not the intersection of these two lines.

400

Is the point (0, -5) a part of the solution for this system of inequalities:

Why or Why not?

y > 2x - 5

y < -3x - 2

No because the line is dotted so the solution doesn't include points on the line.
