Proportional Relationships in tables, graphs, equations

How can you express a proportional relationship using a graph?

• By plotting points that form a straight line through the origin.

• By plotting points that form a curve.

• By plotting points that are randomly distributed.

• By connecting points with a dotted line.

What does it mean if a graph is not linear?

• It represents a constant rate of change.

• It indicates a non-proportional relationship.

• It shows a direct correlation between variables.

• It has a fixed slope throughout.

What does the slope of a graph represent in a proportional relationship?

• The slope represents the constant rate of change between the two quantities.

• The slope indicates the maximum value of the graph.

• The slope shows the total area under the graph.

• The slope represents the average of the two quantities.

What is a proportional relationship?

• A relationship where one quantity is always greater than the other.

• A relationship between two quantities where the ratio of one quantity to the other is constant.

• A relationship that changes over time without any fixed ratio.

• A relationship that only applies to whole numbers.

What is the constant of proportionality?

• The ratio of two quantities that are not related.

• The factor by which one quantity is multiplied to obtain the other in a proportional relationship.

• The difference between two quantities in a proportional relationship.

• The average of two quantities in a proportional relationship.

What is an example of a non-proportional relationship?

• A table where one quantity increases while the other does not maintain a constant ratio.

• A graph that passes through the origin and has a constant slope.

• A situation where two quantities always increase or decrease together.

• A relationship where one quantity is always double the other.

What is the significance of the origin (0,0) in a proportional graph?

• The origin represents that when one quantity is zero, the other quantity is also zero.

• The origin indicates the maximum value of both quantities.

• The origin is irrelevant in proportional graphs.

• The origin shows the point where the two quantities are equal.

Can a table with a zero value in one column represent a proportional relationship?

• No, it cannot represent a proportional relationship.

• Yes, if the other column also has a zero value, it can represent a proportional relationship.

• Only if the zero value is in the first column.

• Yes, but only if the values are negative.
