AlgebraEasyY-intercept of a line in standard form
Algebra practice question
Which of the following is the y-intercept of the graph of 2x + 3y = 12 in the xy-plane?
- A. (0, 4)Correct
- B. (6, 0)
- C. (4, 0)
- D. (0, 6)
Answer: A. (0, 4)
At x = 0, 3y = 12, so y = 4.
Why the other answers are wrong
- B. (6, 0)
- (6, 0) is the x-intercept.
- C. (4, 0)
- (4, 0) puts the y-value on the x-axis.
- D. (0, 6)
- 6 is the x-intercept's value, not the y-intercept's.
