Vertical angles are congruent. your teacher and text may call them opposite angles instead... they are the same thing.
A linear function has 1 as the highest power of the variable.
A. f(x) = 2 - 7x
here, the highest power of the variable x is 1.
Hence it is a LINEAR function.
___________
B. f(x) = 2 + x + x^2
here, the highest power of the variable x is 2.
Hence it is NOT a linear function.
_______________
here, the highest power of the variable x is 1/2.
Hence it is NOT a linear function.

Answer: -14 degrees F
Explanation:
Draw a vertical number line. Plot -3 on that line. Then move down 11 units to arrive at -14. Think of it like being in basement level 3 of a building, going down 11 floors, to get to basement level 14.
Answer:
-1/1 or -1
Step-by-step explanation:
subtract y: 3-4= -1
subtract x: 2-1=1
answer: -1/1
