Which statement is correct for (y=52-4x)?
Answer and explanation
Correct answer: It is linear decay
In y = 52 - 4x, the coefficient of x is -4. When x increases by 1, y decreases by 4, so the relation represents linear decay. It is not a constant function because y changes when x changes. Exam tip: In y = a + bx, a positive b indicates linear growth and a negative b indicates linear decay.
