Reading Graphs
In a graph, there are three things that can help us completely analyze the graph:
TITLE
AXES
RELATIONS BETWEEN AXES: Linearly increasing, Linearly decreasing, or Constant relation
3
Linearly Increasing Relation
A graph relating two quantities is linearly increasing if with the increase in one quantity, the other quantity also increases
4
Linearly Decreasing Relation
A graph relating two quantities is linearly decreasing if with the increase in one quantity, the other quantity decreases.
5
Constant Relation
A graph relating two quantities has a constant relation if with the increase in one quantity, the other quantity does not change i.e. remains constant.
