How can you identify a linear nonproportional relationship from a table, a graph, and an equation?
From a table, for an ordered pair (0,y), y will not be
From a graph, the y-intercept will
not be
From an equation, it will have the form y = mx + b where b is not

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.

Need more information to find the exact intercept and to put it in y=mx+b form
