12/9 Proportion Equation vs Table Test Practice

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

What does 'k' represent in a proportional relationship?

Back

'k' represents the constant of proportionality, which is the ratio of the dependent variable to the independent variable.

Front

How do you determine if a table of values is proportional?

Back

A table is proportional if the ratio of the y-values to the x-values is constant (the same for all pairs).

Front

What is the formula for finding 'k' in a proportional relationship?

Back

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

Front

If k = 4, what does this mean in a proportional relationship?

Back

It means that for every 1 unit increase in x, y increases by 4 units.

Front

What does it mean if there is no 'k' in a table?

Back

It means the relationship is non-proportional, and the ratios of y to x are not constant.

Front

How can you compare two proportional relationships?

Back

You can compare their 'k' values; the relationship with the higher 'k' value increases faster.

Front

What is the significance of the equation y = kx?

Back

This equation represents a direct variation where y varies directly with x, with 'k' as the constant of proportionality.

Front

If y = 0.778x, what can you say about the relationship?

Back

This indicates a proportional relationship where k = 0.778.

Front

What does it mean if two equations have the same 'k'?

Back

It means they represent the same proportional relationship.
