Front

What is the constant of proportionality in a proportional relationship?

Back

The constant of proportionality is the constant factor (k) that relates two variables in a proportional relationship, expressed as y = kx.

Front

How do you find 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 in the table.

Front

What does a scale drawing represent?

Back

A scale drawing represents an object or area with accurate proportions but at a reduced or enlarged size.

Front

If y = kx, what does k represent?

Back

In the equation y = kx, k represents the constant of proportionality, indicating how much y changes for a unit change in x.

Front

What is the relationship between x and y in a proportional relationship?

Back

In a proportional relationship, as x increases or decreases, y changes at a constant rate determined by the constant of proportionality.

Front

How can you determine if two quantities are proportional?

Back

Two quantities are proportional if their ratio remains constant as the values change.

Front

What is the formula for finding the area of a rectangle?

Back

The area of a rectangle is found using the formula: Area = length × width.

Front

If the constant of proportionality is $9 per hour, what does this mean?

Back

It means for every hour, the value of y increases by $9 for each unit of x.

Front

What is a proportional relationship?

Back

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

Front

How do you solve for x in a proportional equation?

Back

To solve for x in a proportional equation, isolate x by dividing or multiplying both sides of the equation appropriately.
