Question

Is `y=1` a linear function?

Answer 1

Yes, it is linear.

Explanation:

There are five conditions which must be met in order for an equation or function to be linear.

1) No variable can have an exponent other than the understood `+1`.
2) No term can have more tan one variable.
3) No variable can be part of the denominator of a fraction.
4) No variable can be inside absolute value lines.
5) No variable can be part of a radicand.

Since `y = 1` meets all these conditions, it is linear.
