Which of the following points lies in the solution region of the inequality 3x − 2y > 6?
This item is invalid because more than one option satisfies the inequality.
- A(1, −2)
- B(2, 0)
- C(4, 3)
- D(5, 4)Correct
Explanation
Substitute each point into 3x − 2y. (1, −2): 3 + 4 = 7 > 6, which is true. Check the others: (2, 0): 6 > 6 is false. (4, 3): 12 − 6 = 6 > 6 is false. (5, 4): 15 − 8 = 7 > 6 is true. So two points satisfy it, which makes this question flawed.

One question tells you little. A timed set on Linear Inequalities shows your real accuracy, how long you take and where you lose marks.
