Question

Starting at noon, Xin observed the amount of snow on her lawn during a blizzard. She created a graph to represent how many inches of snow were on the lawn at x minutes past noon. What is the meaning of the y-value when x, equals, x=60?

Answer 1

The y-value represents the amount of snow on Xin's lawn at a specific time, where x represents the number of minutes past noon. In this case, x = 60 represents 60 minutes past noon, which is equivalent to 1 hour.

So, when x = 60, the meaning of the y-value on the graph would be the amount of snow on Xin's lawn after 1 hour since noon. To determine the specific meaning of the y-value, we would need to refer to the units used on the y-axis of the graph (e.g., inches, centimeters, etc.).

For example, if the y-axis represents the amount of snow in inches, and the y-value at x = 60 is 4 inches, it means that after 1 hour since noon, there was 4 inches of snow on Xin's lawn.
