Constant intervals appear as flat lines parallel to the x-axis.
A constant interval and why it happens
In a graph with several intervals of data, a constant interval appears as a flat line parallel to the x-axis.
This occurs when the y values remains constant for a certain range of values of the x values
A constant interval can be produced by a different scenarios, some examples are:
- A physical constraint
- A constant rate of change
In general, a constant interval indicates that there is no relationship between the x and y values within that range of values.
Question
