They are straight lines through the origin and their gradient is the constant of proportionality.
Do all linear graphs have proportional relationship
Either a straight line through the origin or a hyperbola.
Graphs are pictorial representations of relationships.
Graphs help you see relationships in things such as inflation in money, or rising population.
graphs give a trend of variables and the trend can be studied using the the extent they usually portray and the graphs are not emperical methods they give interpolated relationships hence a reduced uncertainities
Do all linear graphs have proportional relationship
They aren't.
Either a straight line through the origin or a hyperbola.
Graphs are pictorial representations of relationships.
For proportional relationships the ratio is a constant.
graphs
When graphs are used correctly, they do make relationships easier to understand. they provide a useful way to visualize relationships.

The answer is numbers

Graphs are a convenient way to display relationships between variables.
