A line has a slope of 3 and passes through the point (0; 2). What is its equation?
- A. y = 3x + 2 ✓
- B. y = 2x + 3
- C. y = 3x - 2
- D. y = -3x + 2
Correct answer
A. y = 3x + 2
Explanation
In slope-intercept form y = mx + b; the slope m = 3 and the y-intercept b = 2 (since the line passes through (0;2)); giving y = 3x + 2.
