Mathematics · Linear Equations
Which of the following systems of linear equations has a unique solution at the intersection point (-2, 3) and passes through the intercepts representing the lines 2x + y + 1 = 0 and x - 2y + 8 = 0?
- 12x + y + 1 = 0, x + 2y + 8 = 0
- 22x + y + 1 = 0, x - 2y + 8 = 0✓
- 32x - y + 1 = 0, x + 2y + 8 = 0
- 42x - y + 1 = 0, x - 2y + 8 = 0
Correct answer
2x + y + 1 = 0, x - 2y + 8 = 0
