In the line (y=21-8x), what are the coefficient of (x) and the constant term?
Answer and explanation
Correct answer: Coefficient of x −8, constant term 21
The equation is y = 21 − 8x, which can also be written as y = −8x + 21. The number multiplying x is −8, so the coefficient of x is −8. The term without x is 21, so it is the constant term. Option B misses the negative sign. Exam tip: a negative sign before a term is part of its coefficient.
