Practice Test for Math 6 ACC Unit 6: Linear Representations

Front

What is a linear representation?

Back

A linear representation is a way to show the relationship between two variables using a straight line on a graph, where one variable is dependent on the other.

Front

What does the constant of proportionality represent?

Back

The constant of proportionality is the ratio that relates two proportional quantities, indicating how much one quantity changes in relation to another.

Front

In the equation c = g + 8.00, what do c and g represent?

Back

In this equation, c represents the total cost, and g represents the number of groceries.

Front

What is an independent quantity?

Back

An independent quantity is a variable that stands alone and is not affected by other variables in an experiment.

Front

What is a dependent quantity?

Back

A dependent quantity is a variable that depends on the value of another variable in an experiment.

Front

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

Back

To find the constant of proportionality, divide the dependent variable by the independent variable for any pair of values in the table.

Front

What is the formula for a proportional relationship?

Back

The formula for a proportional relationship is y = kx, where k is the constant of proportionality.

Front

If the cost of 3 pounds of grapes is $9.51, how do you find the cost per pound?

Back

To find the cost per pound, divide the total cost by the number of pounds: $9.51 ÷ 3 = $3.17.

Front

What does the equation v = 40d represent?

Back

The equation v = 40d represents the relationship between the number of viewers (v) and the number of days (d), indicating that for each day, there are 40 viewers.

Front

What is the significance of a table in representing data?

Back

A table organizes data in rows and columns, making it easier to analyze relationships between different variables.
