About this MCQ
Medium SAT item. Correct choice: A. y = 3x + 2.
- A. y = 3x + 2 ✓
- B. y = 2x + 3
Why not B: “y = 2x + 3” is not y = 3x + 2.
- C. y = 3x - 2
Why not C: “y = 3x - 2” is not y = 3x + 2.
- D. y = -3x + 2
Why not D: “y = -3x + 2” is not y = 3x + 2.
Correct answer
A. y = 3x + 2
Explanation
y = 3x + 2 (option A) is the accepted answer to “A line has a slope of 3 and passes through the point (0; 2). What is its equation”. Option B (y = 2x + 3) is a different value from y = 3x + 2. Option C (y = 3x - 2) is a different value from y = 3x + 2. Option D (y = -3x + 2) is a different value from y = 3x + 2. Keep y = 3x + 2 as the SAT fact for this stem.
