Algebra
An open or closed circle are used to graph an inequality in one variable. An open circle is used if the value at the end point is excluded from the feasible region while a closed circle is used if the value at that point is within the accepted region.

A function can only have one output for any given input. This means that any x value you choose cannot have multiple corresponding y values. The vertical line test involves looking at a graph and drawing vertical lines over it. If any of the vertical lines you have drawn touch the graph of the function more than once, then the graph does not represent a function.
This graph fails the vertical line test at x = 3This graph is not the graph of a function.
Depending on the comparison operator used, that's either an equation, or an inequality.
Bar Graph
A pie graph would represent the composition of air nicely.
Bar graph for amounts. Histogram for amounts over a certain amount of time.
An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
Any type of graph, really.
You could try a speed-time graph, or a distance-time graph.

Hi lo graph
A line graph.
