A value that does not change.

A value that does not change.

• A. Variable
• B. Parameter
• C. Constant
• D. Coefficient

Answer: (C)

A value that does not change is a constant. In algebra, variables are symbols that can take different values, while a constant stays fixed no matter what the variable does. For example, in an expression like y = 2x + 5, x can vary, but the number 5 does not depend on x and remains the same; that makes 5 a constant term. The number 2 is a coefficient, a fixed multiplier of x, but the general idea this question targets is the term that does not change—constant. A parameter is a value fixed for a particular scenario to study its effects, but it isn’t the standard label for a value that remains unchanged within a single expression.
