Algebra practice question
Which of the following is the equation of the line in the xy-plane that passes through (0, 3) and has the same slope as the line y = 2x − 9?
- A. y = 2x + 3Correct
- B. y = 3x + 2
- C. y = 2x − 9
- D. y = −9x + 3
Answer: A. y = 2x + 3
Slope 2 from the given line, and y-intercept 3 from the point (0, 3).
Why the other answers are wrong
- B. y = 3x + 2
- Slope and intercept swapped.
- C. y = 2x − 9
- The given line itself, which passes through (0, −9).
- D. y = −9x + 3
- Uses −9 as the slope.
