Question

Which is the best definition of coefficient?

Two terms that have the same variable.
A symbol that you can use to represent unknown or changeable quantities
A number that is placed in front of the variable.
Two single terms separated by a plus sign.

Answer 1

Any number placed in front of a variable/with a variable

Answer 2

A number that is placed in front of the variable.

Step-by-step explanation:

By definition, a coefficient is the number that is placed in front of the variable.

For example, given the equation

3x + 2y - 7 = 9

The 3 and 2 would be coefficients because they are the numbers placed in front of the variables.

The x and y would be variables because they are symbols used to represent unknown or changeable numbers.

The 7 and 9 would be constants because they are set numbers which cannot be changed without changing the entire equation.
