Independent events. Someone does not have to buy popcorn to buy a drink and someone does not have to buy a drink to buy popcorn.
Answer:
Step-by-step explanation:
E(-1,6) & F(-2,-10)
![Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\ \ \ \ = \frac{-10-6}{-2-[-1]}\\](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%5C%20%20%5C%20%20%5C%20%5C%20%3D%20%5Cfrac%7B-10-6%7D%7B-2-%5B-1%5D%7D%5C%5C)

Slope of the line perpendicular to this line = -1/m = -1/16
The answer is 30.You get th is by multiplying 4 by 3 first than the answer by 2.5.Which gives your final answer 30.
