Supplementary angles are those angles that measure up to 180 degrees. For example, angle 130° and angle 50° are supplementary because on adding 130° and 50° we get 180°. Similarly, complementary angles add up to 90 degrees. ... Hence, any two angles can be supplementary, if their sum equal to 180°.
The function is not defined when the denominator (x-9) is zero. The denominator will be zero when x=9, so that value must be excluded from the domain.
The domain is ...

Answer:
x + y = -1
Step-by-step explanation:
To write the equation of a line, find the slope and use it with a point in the point slope form.
You can find the slope using the slope formula.

Substitute m = -1 and the point (2,-3) into the point slope form.

Convert to standard form by applying the distributive property and rearranging the terms.
y+3 = -1(x-2)
y + 3 = -x + 2
x + y + 3 = 2
x + y = -1
