Algebra practice question

Answer: C. 6

The line crosses the y-axis where x = 0: 2y = 12, so y = 6. Choice B (4) is the x-intercept (set y = 0), which answers the wrong axis.

Why the other answers are wrong

A. 2

2 is just the coefficient of y in the equation, not the y-intercept; set x = 0 to get 2y = 12, then divide to get y = 6.

B. 4

4 is the x-intercept: you set y = 0 and solved 3x = 12. The y-axis crossing happens where x = 0.

D. 12

You substituted x = 0 correctly to get 2y = 12 but stopped there — divide both sides by 2 to get y = 6.
