Time is your independent variable, and snowfall is your dependent variable.
Slope can be found by calculating ∆y/∆x:

Snowfall will accumulate 0.02 m every hour.
The power rule (or law of indices) related to root is given
![x^{ \frac{1}{2} }= \sqrt[2]{x}](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%20%20%5Csqrt%5B2%5D%7Bx%7D%20%20)
We have

Rewrite according to the rule we have

The exponent on y is '1'
Answer:
Step-by-step explanation:
it switches the x and y coordinates and places a negative on the new x
P=(x,y)
90° CCW rotation P'(-y,x)
A because that's the only one that makes sence
