What is the definition of proportional relationships in graphs?
Either a straight line through the origin or a hyperbola.
Do all linear graphs represent proportional relationalships?
Not all linear graphs represent proportional relationships. A proportional relationship is one where the graph passes through the origin (0,0), indicating that when one variable is zero, the other is also zero. Linear graphs can represent relationships that have a constant rate of change but do not necessarily pass through the origin, indicating a non-proportional relationship. Therefore, while all proportional relationships are linear, not all linear relationships are proportional.
How do you evaluate graphs of proportional relationships?
They are straight lines through the origin and their gradient is the constant of proportionality.
Do linear graphs represent proportional relationships?

What are the properties of proportional and non-proportional tables and graphs?
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.

How can you show that two objects are proportional with an equation?
You can use a plot diagram to plot the points and if they all go straight through the origin then it is proportional

How are proportional and non proportional linear relationships different?
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.
What are proportional relationships in graphs?
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.
How are proportional and non proportional relationships similar?
They aren't.
Are trends best observed in scatter plots line graphs or circle graphs?
scatter plot and line graph
How are using graphs equations and tables similar when distinguishing between proportional and nonproportional situations?
Graphs, equations, and tables are all effective tools for distinguishing between proportional and nonproportional situations because they visually and numerically represent relationships between variables. In proportional situations, graphs yield straight lines through the origin, equations take the form (y = kx) (where (k) is a constant), and tables show consistent ratios between paired values. In contrast, nonproportional situations exhibit curves or lines that do not pass through the origin, equations may contain additional constants or terms, and tables reveal varying ratios. Thus, each method provides unique insights into the nature of the relationship.
What ways can graphs be helpful in?
graphs can be helpful because you can create graphs and you can plot numbers on them. They help you find so many different things ! an example is if i have the numbers 1,2,3,4,5,6 you can plot these numbers on a graph. It can also show a change, or record something for a amount of time.
