Is 3y a constant, variable, or coefficient

y is a variable

Step-by-step explanation:

Algebraic Equations has Terms, Coefficients, Constants

Terms:

Terms can be expressed as a algebraic expression separated by addition or subtraction (+, - ) symbols.ie, positive and negative terms

Example:

An algebraic expression is here 4x and 3y are terms

Constant:

A constant term is a number with no variable factors. It is a term whose value never varies remains stable.

Example:

An algebraic expression is here 6 is the constant and it may not vary

Variables, constants, coefficients:

Variable:

A variable is a symbol or usually letter/letters  used to represent:

a) an unknown quantity or number

b) any one of many numbers to indicate a general principle.

Example:

An algebraic expression is here x anb y are variables. it may vary as variable varies

Constant:

A constant is a single number.

Coefficient:

A coefficient is a number which is in before of a variable.

Example:

An algebraic expression is here coefficient of x is 1 and coefficient of y is 6

Comparing  3y with definitions of Variables, constants, coefficients  we get 3y is not a constant or coefficient.

So that y is a variable.

Therefore given y is a variable.

is only a line? i think so

this answer is !
