Answer :
The answer is y=0.5x+3
There are 3 inches of snow on the ground: y = 3
When it begins to snow 0.5 inches per hour: y = 0.5x
There are 3 inches of snow on the ground when it begins to snow 0.5 inches per hour: y = 0.5x + 3
There are 3 inches of snow on the ground: y = 3
When it begins to snow 0.5 inches per hour: y = 0.5x
There are 3 inches of snow on the ground when it begins to snow 0.5 inches per hour: y = 0.5x + 3
