Which rule has initial value (18) and growth rate (6)?

Answer and explanation

Correct answer: \(y=18+6x\)

A linear rule has the form \(y=a+bx\), where \(a\) is the initial value and \(b\) is the rate of growth or decay. In \(y=18+6x\), the constant term is \(18\) and the coefficient of \(x\) is \(+6\), so it represents growth. Option B has \(-6\), which represents decay. Exam tip: identify the constant term for the initial value and the coefficient of \(x\) for the rate.
