Plot each point on a graph , then count how many you need to go up and then over in this case it is 8 over 1 then calculate the y int so y= 8x -25
The angle would be 35 degrees (the complement is 90-35 = 55 degrees.) Hope this helps!

Answer:
-1/18
Step-by-step explanation:
Let's multiply left and right by 3n:
2 = -12 * 3n =>
-36n = 2
now divide by -36:
n = 2/-36 = -1/18
If 
, then 
and 
because 
lies in the fourth quadrant.
By DeMoivre's theorem,
so the answer is B.
