For this case we have that by definition, a linear equation is of the form:

The variable (s) involved in the equation always have exponent 1.
Some examples of linear equations are:

Answer:
In a linear equation the variables have exponent 1.

A Non-example is like there we not enough to grapha
J because this is a quadratic function which is shaped like a u upward
Well the increase is 132/120. Simplify by dividing 12 from the numerator and the denominator, you should get 11/10.
11/10 is also 110%
