Is It Proportional?

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant. This means that as one quantity increases or decreases, the other quantity does so in a consistent manner.

What does it mean for a graph to pass through the origin?

Back

A graph passes through the origin if the point (0,0) is on the graph. This indicates that when the independent variable is zero, the dependent variable is also zero.

Front

How can you determine if a graph is proportional?

Back

A graph is proportional if it is a straight line that passes through the origin.

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is a relationship where the ratio between two quantities is not constant, often represented by a graph that does not pass through the origin.

Front

What does it mean if a graph is nonlinear?

Back

A nonlinear graph is one that does not form a straight line. This indicates that the relationship between the variables is not constant.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis. It represents the value of the dependent variable when the independent variable is zero.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a graph that represents the independent variable.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a graph that represents the dependent variable.

Front

What does it mean for a graph to intersect the x-axis?

Back

A graph intersects the x-axis at the point where the dependent variable is zero, indicating the value of the independent variable at that point.

Front

What is a straight line graph?

Back

A straight line graph represents a linear relationship between two variables, indicating a constant rate of change.
