Answer:
1. Slope = -2 , y-intercept = 1
2. Slope = 5 , y-intercept = -15
3. Slope = 1.5 , y-intercept = -2
4. Slope = -3 , y-intercept = 9
Step-by-step explanation:
1. The slope is -2 because using the formula y₁-y₂÷x₁-x₂ you can use the points given to you to get -2. It doesn't matter which one you pick as y1 or y2, just make sure you keep it consistent with the x numberings. I did 1--3 (which becomes 1+3) and 0-2. Those equal 4/-2 which gives you -2. Use these same steps for all of them, but with ones that don't have the points given, just pick two that are whole numbers and not decimals. For finding the y-intercept, just find the point that is on the y axis line. It is given on number one as (0,1). So, the y-intercept is 1. Hope this helps!

Answer:
The mean hourly snowfall is 2.5 centimeters
Step-by-step explanation:
The mean hourly snowfall is the number of centimeters that fell during the period divided by the number of hours.
From 5 P.M. to 9 P.M., there are 4 hours
At 5 P.M., the total snowfall is 2 centimeters.
At 9 P.M., the total snowfall is 12 centimeters.
So in those four hours, the depth of snow increases 12-2 = 10 centimeters
10/4 = 2.5
The mean hourly snowfall is 2.5 centimeters
