If (y=20+0x), what type of value does it show?
Answer and explanation
Correct answer: Constant value
Here, y=20+0x simplifies to y=20. Since the coefficient of x is 0, the value of y does not change when x changes, so it represents a constant value. Linear growth or decay requires a non-zero positive or negative coefficient of x, respectively. Exam tip: if the coefficient of x is 0, the expression is constant.
