AlgebraEasy–MediumLine with the same slope
Algebra practice question
Which of the following lines has the same slope as the line y = 4x − 1?
- A. y = 4x + 6Correct
- B. y = −4x − 1
- C. y = x/4 − 1
- D. y = −x/4 + 3
Answer: A. y = 4x + 6
The slope is the coefficient of x, and only y = 4x + 6 also has slope 4.
Why the other answers are wrong
- B. y = −4x − 1
- Slope −4.
- C. y = x/4 − 1
- Slope 1/4.
- D. y = −x/4 + 3
- Slope −1/4.
