Unit Rate and Constant of Proportionality 2

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together. It expresses how many units of one quantity correspond to one unit of another quantity.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) in the equation y = kx, which shows the relationship between two proportional quantities.

Front

How can you determine if a graph represents a proportional relationship?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

In the equation y = kx, what does 'k' represent?

Back

In the equation y = kx, 'k' represents the constant of proportionality, which indicates the ratio of y to x.

If Janet used 155 beads to create 5 necklaces, how many beads did she use for each necklace?

Back

31 beads per necklace.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio or rate.

Front

What is the formula for finding the constant of proportionality?

Back

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

Front

What type of line represents a proportional relationship on a graph?

Back

A straight line that passes through the origin.

Front

If y = 14x, what is the constant of proportionality?

Back

14.

Front

What is the relationship between unit rates and constant of proportionality?

Back

Unit rates are specific examples of the constant of proportionality, representing the ratio of one quantity to one unit of another.
