Module 5 review

Front

What is the equation for a proportional relationship where y increases as x increases?

Back

A proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Front

Define the constant of proportionality.

Back

The constant of proportionality is the constant factor that relates two proportional quantities, often represented as k in the equation y = kx.

Front

What does it mean if a relationship is proportional?

Back

A relationship is proportional if the ratio of the two quantities remains constant.

Front

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

Back

To find the constant of proportionality, divide the value of y by the corresponding value of x for any pair of values.

Front

What is the equation for a proportional relationship if the constant of proportionality is 1.75?

Back

Front

If y = 5x, what is the constant of proportionality?

Back

The constant of proportionality is 5.

Front

How can you compare the rates of two different producers based on their output?

Back

You can compare their rates by looking at the number of items produced per unit of time.

Front

What does it mean if two companies produce at the same rate?

Back

It means they produce the same number of items in the same amount of time.

Front

If Sally the sloth moves according to the equation y = 2x and Jordan moves according to y = 3x, who is faster?

Back

Jordan is faster because his equation has a higher coefficient.

Front

What is the significance of the slope in a linear equation?

Back

The slope represents the rate of change of y with respect to x.
