Answer:
Slope: 1 Y-intercept: 3 Y=1x+3 Change: y=1x
Explanation:
The slope would be 1 because it is going at a constant rate. The Y-intercept would be 3 because it was already at 3 inches from last week's snow storm. The equation would change from y=1x+3 to y=1x because there wouldn't be 3 inches of snow from the snow storm.
