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.
graphs
Relationships that can be represented in graphs include linear relationships, quadratic relationships, exponential relationships, and inverse relationships. Each type of relationship has a distinct pattern when graphed, allowing for visual representation and analysis of the data.
The answer is numbers
Graphs help you see relationships in things such as inflation in money, or rising population.
Graphs are a convenient way to display relationships between variables.
