What terminology do we use to describe the 𝑦 in 16𝑦?

The term 16𝑦 has two parts, 16 and 𝑦. 𝑦 is a variable as its quantity may change. A variable is a symbol for a number we don’t know yet. It is usually a letter like 𝑥 or 𝑦. The 16 in this expression is the coefficient of 𝑦. It is the number we’re multiplying 𝑦 by. If, on the other hand, our expression had been 16 plus 𝑦, the 16 would be a constant. This is because its value never changes. The correct answer to this question is “variable.” The terminology we use to describe the 𝑦 in 16𝑦 is a “variable.”
