Step-by-step explanation:
From the graph,
- After 1 hour passed, 2 inches of show fell
- After 5 hours passed, 10 inches of snow fell
- And so on
This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is

where k is the slope
Find k:

so the equation is
and the slope is k = 2.
The slope means how many inches of snow fell in 1 hour.
In 1 hour, 2 inches of snow fell.
