Do all linear graphs have proportional relationship
Either a straight line through the origin or a hyperbola.
They are straight lines through the origin and their gradient is the constant of proportionality.
Graphs are pictorial representations of relationships.
Graphs help you see relationships in things such as inflation in money, or rising population.
