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.
Proportional relationships in graphs are represented by straight lines that pass through the origin (0,0). In these relationships, the ratio of the two quantities remains constant, meaning that as one quantity increases or decreases, the other does so in a consistent manner. This can be visually identified by the slope of the line, which represents the constant ratio. Overall, proportional relationships illustrate a direct correlation between two variables.
Proportional and non-proportional relationships both describe how two variables interact and change in relation to one another. In both types of relationships, changes in one variable can affect the other, and they can be represented graphically, typically with a line. However, while proportional relationships maintain a constant ratio between the variables, non-proportional relationships do not, leading to different patterns in their graphs. Both are essential for understanding mathematical concepts and real-world applications.
Graphs are pictorial representations of relationships.

Proportional linear relationships have a constant ratio between the two variables and pass through the origin (0,0), meaning that if one variable is zero, the other is also zero. In contrast, non-proportional linear relationships do not have a constant ratio and do not necessarily pass through the origin; they include a y-intercept that is not zero, indicating a fixed value when the independent variable is zero. This results in different graphs, with proportional relationships forming straight lines through the origin and non-proportional relationships forming straight lines that intersect the y-axis at a point other than the origin.
A non-proportional relationship refers to a type of relationship between two variables where the ratio between them is not constant. In such relationships, as one variable changes, the other may change, but not in a consistent or predictable manner that maintains a fixed ratio. Unlike proportional relationships, where doubling one variable results in a doubling of the other, non-proportional relationships can vary widely, often depicted in graphs as curves or lines that do not pass through the origin.
Tables, graphs, and equations are essential tools for working with proportions as they provide clear and organized ways to visualize relationships between quantities. Tables allow for easy comparison of values, making it straightforward to identify proportional relationships. Graphs illustrate these relationships visually, helping to identify trends and patterns. Equations enable precise calculations and manipulations, facilitating the solving of proportion-related problems.
graphs
For proportional relationships the ratio is a constant.
Graphs, equations, and tables are all tools used to represent and analyze relationships between variables, particularly when distinguishing between personal and proportional linear relationships. In both cases, a linear relationship can be identified by a straight line on a graph, a linear equation in the form of (y = mx + b), and a table that shows a constant rate of change between values. For proportional relationships, the line passes through the origin (0,0), while personal relationships have a y-intercept that is not zero. Thus, each method can effectively illustrate the nature of the relationship being examined.
