Which rule is linear growth and also has initial value (24)?

Answer and explanation

Correct answer: (y=24+7x)

The direct answer is option C, \(y=24+7x\). A linear rule has the form \(y=mx+c\), where \(m\) is the constant rate of change and \(c\) is the value when \(x=0\). Growth means \(m>0\), and the initial value 24 means \(y=24\) at \(x=0\). In C, the intercept is 24 and the slope is +7, so both conditions hold. Option A has initial value 24 but slope −7, so it describes linear decay. Option B has positive growth but starts at 7, not 24. Option D starts at 24 but contains \(x^2\), so its rate is not constant and it is not linear. Memory cue: positive coefficient of \(x\) means growth; the constant term is the initial value.
