ACTIVITY 1

Tell whether the following is a linear inequality in two variables or not.

1. 3x + 6y <12
2. 2y < 8x – 4
3. y = 3x + 5
4. 9x + 4y ≤ - 15
5. 3x + 4y = 10
6. 8x² – 4y ≥ 10
7. 4x + 8y ≥ 12
8. 4x + 5y > 20
9. 5x – 10 ≤ 4
10. 2x = 4y -2


ACTIVITY 2


Determine whether each ordered pair is a solution of 2x + 3y ≤ 7. Show your solution.


1. (0,1)
2. (-4,0)
3. (1,0)
4. (-5,1)
5. (2,-1)
