Question

State the independent variable and dependent variable and find the slope.

Answer 1

Time is your independent variable, and snowfall is your dependent variable.

Slope can be found by calculating ∆y/∆x:
$x = \frac{0.06 - 0.02}{3 - 1} \\ x = \frac{0.04}{2} \\ x = 0.02$

Snowfall will accumulate 0.02 m every hour.
