What type of rule is (y=9+0x)?
Advertisement
Answer and explanation
Correct answer: Constant value
Here, the coefficient of x is 0, so y remains 9 even when x changes. Therefore, this is a constant-value rule. In linear growth or decay, the coefficient of x is non-zero. Exam tip: In y=a+bx, the rule is constant when b=0.
