A
There is no variable (x or y) that is raised to any power but 1. This is linear.
B
One thing you could do and that is try to graph it. The table is entered below. I haven't made the table yet, so I don't know if it is linear or not. My instincts tell me not. And that turns out to be correct. It looks like a quadratic of some kind. The diagram on the right is a better picture of the quadratic.
Answer:
You can use multiplication to check your division answer this way.
Do the division problem.
Multiply the quotient times the divisor.
If there is a remainder, add it to the multiplication product.
Compare this answer to the dividend. They should be the same number (630 = 630).

Answer:
-x aka -1
Step-by-step explanation:
x1 y1 x2 y2
9 -2 4 3
m= y2 - y1/x2 - x1
m = 3 + 2/4 - 9
(The "-" sign turned positive because it is negative times negative)
5/-5
Simplify: 5/-5 = -1 = -x
The slope of this line is -x
a + b - c = 180
add both sides by c
a + b - c + c = 180 + c
simplifying
a + b = 180 + c
subtract 180 from both sides
a + b - 180 = 180 + c - 180
simplifying
a + b - 180 = c
Answer
c = a + b - 180
