1. Which of the following is a linear Inequality in two variables.

a. X+V>5
b. y> 5
c. y + 156
d. 4x-5-3 2

2. If the graph of a linear equation in two variables is a straight line, then what can you say about the graph of a linear inequality in two variables?

a. It is a broken line
b. It is a hall-plane
c. It is a half parabola
d. It is a parabola

3. Which of the following ordered pairs satisfy both 2x + 5y < 10 and 3x -4y≥-8?

a. (3,5)
b.(5,0)
c. (1,0)
d. (0,2)

4. What is the boundary line for a linear inequality involving symbols ≤ or ≥ in two variables.

a. broken
b. solid
c. straight
d. curve

5. If your classmate insisted that (4,5) is a solution of x - 3y ≤-6. Do you agree with your classmate?

a. Yes, because I believe whatever the answer of my classmate.
b. Yes, because after substituting (4,5) to the inequality, it makes the statement true.
c. No, because after substituting the value of x and y to the inequality the answer is -11 >-5 which is a false statement
d. No, because my friend told me that the answer is wrong.​​
