7. Which ordered pair is a solution of 2x – 3y = 24?
(-6, 4) (-6, -4) (6, -4) (6, 4)
Why is the point you chose a solution?

8. Make a table and graph. Hint: Pay attention to the domain.
y = -3x + 1
Domain: {-1, 0, 1, 2} x y
Is this graph discrete or continuous?
State the range.

9. Make a table and graph. Hint: Pay attention to the domain.
f(x) = -x + 2
Domain: x > 0 x
f(x)
State the range.
Is this graph discrete or continuous?

10. Sometimes you need to solve for y and then graph
2x - y = 4
Domain: {-1, 0, 1, 2} x
f(x)
State the range.
Is this graph discrete or continuous?

11. Graph: 3x + 2y = 6 y x 3x + 2y = 6 Domain: {x x < 0}
State the range.
