What is the coefficient of (x) in the line (y=-9x+16)?
Answer and explanation
Correct answer: -9
In y = -9x + 16, the number multiplying x is -9, so the coefficient of x is -9. The number 16 is the constant term, not the coefficient of x. In this form, -9 also represents the slope of the line. Exam tip: the number that directly multiplies a variable is its coefficient.
