If a function is non-linear, there must be an exponent in the equation. For example, [tex]x^{2}[/tex] or [tex]x^{3\\}[/tex].
Since this function has no exponent attached to the x-variable, we can assume this function is linear.
Based on the on the equation given: 9x + y = 12
The y-intercept will be 12.
To determine the x-intercept, we set y equal to zero and solve for x.
9x + 0 = 12
9x = 12 ⇒ divide both sides by 9
x = 1.333
Therfore, the x-intercept will be 1.33
