Which of these inequalities is represented by the shaded portion of the graph?
- A. 2y + x - 3< 0
- B. 2y - x - 3< 0
- C. 2y - x + 3< 0
- D. 2y + x +3< 0
Correct Answer: B. 2y - x - 3< 0
Explanation
(0, 1.5), (-3, 0)
m = \(\frac{0 - 1.5}{-3, 0}\) = 0.5
0.5 = \(\frac{y - 1.5}{-3.0}\) = 0.5
y = 0.5x + 1.5
2y = x + 3
2y - x - 3 < 0
