How can you identify a linear nonproportional relationship from a table, a graph, and an equation?

Zarrin [17]

On-proportional linear relationships can be expressed in the form y = mx + b, where b is not 0, m represents the constant rate of change or slope of the line, and b represents the y-intercept. The graph of a non-proportional linear relationship is a straight line that does not pass through the origin.
