Algebra practice question
In the xy-plane, the line y = mx + 2, where m is a constant, passes through the point (3, 11). What is the value of m?
Answer: 3
11 = 3m + 2 gives 3m = 9, so m = 3.
Common wrong answers
- If you answered 9
- 9 is 3m, not m.
- If you answered 13
- 13 adds instead of subtracting the 2.
- If you answered 3.67
- 3.67 divides 11 by 3, forgetting the intercept.
