7TH PERIOD-CBA REVIEW 3.5

Front

Does this graph represent a proportional relationship?

Back

Yes, a proportional relationship is one where the ratio of the two variables remains constant.

Front

Is this equation proportional or non proportional?

Back

Proportional. An equation is proportional if it can be expressed in the form y = kx, where k is a constant.

Front

What is the y-intercept?

Back

The y-intercept is the point where the graph intersects the y-axis. In this case, it is -3.

Front

Does the table represent a proportional relationship?

Back

Yes, a table represents a proportional relationship if the ratios of the corresponding values are constant.

Front

Does this graph represent a proportional relationship?

Back

No, if the graph does not pass through the origin or does not maintain a constant ratio, it is not proportional.

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship can be identified if the graph is a straight line that passes through the origin.

Front

What does it mean if an equation is non-proportional?

Back

An equation is non-proportional if it cannot be expressed in the form y = kx, meaning it does not maintain a constant ratio.

Front

What is the significance of the slope in a proportional relationship?

Back

The slope represents the constant ratio between the two variables in a proportional relationship.

Front

How do you find the y-intercept from an equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.
