Answer 1

Answer: nonlinear

Answer 2

Answer:

Linear

Step-by-step explanation:

================================================

I am assuming that you mean:

$y = x + 9$

================================================

Since the equation does not contain an exponent, nor has 'x' as a denominator in a fraction, it is a linear equation.

You can also tell that it's linear because it's in slope-intercept form.

================================================

Hope this helps.
