There are 3 in. of snow on the ground when it begins to snow 0.5 in./h.
Initial depth of snow = 3 in.
it begins to snow 0.5 in./h. The constant rate of snow is 0.5. So slope = 0.5
Let x be the number of hours
y be the total depth of the snow
To frame linear equation we use y=mx+b
where m is the slope and b is the y intercept (initial depth of snow)
We know m=0.5 and b=3
Replace it in the equation
y = 0.5x + 3
The linear equation that represents the total depth of the snow(y), in inches, after x hours
is y= 0.5x + 3
Answer:
Part 1)

Answer:
-1/2
Step-by-step explanation:
rise over run
rise is -2
run is 4
(-2/4)/2=(-1/2)
hope this helps :3
if it did pls mark brainliest
Slope is 1 bc u see where the points are and go up until u find the other point
