Semester 1 Exam Practice Part 2

Front

What is a proportional relationship?

Back

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

Front

What does it mean if a table is non-proportional?

Back

A non-proportional table means that the ratios of the quantities do not remain constant.

Front

How do you determine the constant of proportionality from a table?

Back

To find the constant of proportionality, divide one quantity by the corresponding quantity in the other column.

Front

What is the constant of proportionality if the ratio is 13.5?

Back

The constant of proportionality is 13.5, meaning for every unit increase in one quantity, the other quantity increases by 13.5.

Front

How can you identify a proportional relationship from a graph?

Back

A proportional relationship on a graph is represented by a straight line that passes through the origin (0,0).

Front

What is the constant of proportionality if the ratio is 7.5?

Back

The constant of proportionality is 7.5, indicating that for every unit increase in one quantity, the other quantity increases by 7.5.

Front

What does it mean if a table is proportional?

Back

A proportional table means that the ratios of the quantities remain constant across the table.

Front

How do you find the constant of proportionality from a graph?

Back

To find the constant of proportionality from a graph, calculate the slope of the line, which represents the ratio of the change in the y-value to the change in the x-value.

Front

What is the constant of proportionality if the ratio is 12.5?

Back

The constant of proportionality is 12.5, meaning for every unit increase in one quantity, the other quantity increases by 12.5.

Front

What is the formula for finding the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality, y is the dependent variable, and x is the independent variable.
