Answer:
Look at solution
Step-by-step explanation:
Remember that the x-axis is the time so you start at 0. The y-axis is the amount of snow so it says it starts at 1 inch so you start at (0,1).
When using coordinates remember (x,y) the x is the horizontal axis and y is vertical.
The next few steps deal with slope. The slope is always rise/run. so when it says it snowed for an average of 1 inch per hour, you go one up and one to the right to create the line. When it stopped snowing, the snow (i assume) stays the same so you just have a horizontal line for 5 hours indicating the same amount of snow. Then the snow becomes 3 per hour so you have to go up 3 from where you left off and over 1. Do that for 7 hours.
I hope you read this explanation because this is the basics of graphing. Next time you can try it by yourself :)
