Do these coordinates represent a function or not a function? Why?
(3, 7), (6, 5), (12,9), (6, 10), (18, 10)
This is NOT a function
because the input: x value 6 has more than one output: y.

There was already 3 inches of snow on the ground. Then it snowed at a constant rate of 2 inches per hour.
Use the equation y = 2x + 3 to tell how much snow is on the ground after 2 hours and after 4 hours.
x = 2 hours, y = 7 inches
x = 4, y = 11 inches
