Algebra practice question

The graph of 4x + 6y = 24 crosses the x-axis at the point (a, 0). What is the value of a?

Answer: 6

Set y = 0: 4a = 24, so a = 6.

Common wrong answers

If you answered 4
4 is y at x = 0 (the y-intercept), not the x-intercept.
If you answered 24
24 is the constant term; divide by the x-coefficient: 24 ÷ 4 = 6.
If you answered 2/3
2/3 is the slope magnitude, not where the graph meets the x-axis.
