Direct Relationship Graph Example. A bigger diameter means a bigger circumference. A graph is a useful tool in mathematics.
In example 1 E varies _____ with the number of hours. If X 3 then Y 67. Speed which is an inverse relationship.
The graph below shows a strong negative relationship between two sets of data points plotted on the graph.
Note that as X increases Y decreases in a non-linear fashion. A bigger diameter means a bigger circumference. In example 1 E varies _____ with the number of hours. Not every equation represents a direct variation or a direct proportion.
