Description: Learn how to read and understand graphs of proportional relationships. Let's get some practice interpreting graphs of proportional relationships. This says the proportion relationship between the distance driven and the amount of time driving shown in the following graph, so we have the distance driven on the vertical axis, it's measured in kilometers, then we have the time driving and it's measured in hours along the horizontal axis. If we have zero time, then we have zero distance, and we can also see that it's a line, then it's a linear relationship.*Teacher Advisor is 100% free.
