Which statement is correct for (y=48-6x)?
Answer and explanation
Correct answer: It represents linear decay
The equation y=48-6x is linear, and the coefficient of x is -6. This means that when x increases by 1, y decreases by 6, so it represents linear decay. It is not a constant function because y changes with x. Exam tip: In a linear equation y=a+bx, a positive b indicates growth and a negative b indicates decay.
