Unit Rates from Ordered Pairs, Tables and Graphs

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (X,Y).

Front

How do you identify the unit rate from a table?

Back

The unit rate is found by dividing the total amount by the number of units, giving the amount per one unit.

Front

What does the constant of proportionality represent?

Back

The constant of proportionality is the ratio between two quantities that remain constant, often represented as the unit rate.

Front

How do you calculate the unit rate from a given scenario?

Back

To calculate the unit rate, divide the total quantity by the number of units. For example, if 8 apples cost $4, the unit rate is $4/8 = $0.50 per apple.

Front

What is the unit rate for 10 miles in 2 hours?

Back

The unit rate is 10 miles / 2 hours = 5 miles per hour.

Front

How can you represent a unit rate on a graph?

Back

A unit rate can be represented as the slope of a line on a graph, showing the relationship between two quantities.

Front

What is the significance of the point (0,0) in a graph?

Back

The point (0,0) is the origin, where both the x-axis and y-axis intersect, representing zero values for both quantities.

Front

How do you find the unit rate for a price of $6 for 4 pounds of bananas?

Back

Divide the total price by the total weight: $6 / 4 pounds = $1.50 per pound.

Front

What is the unit rate for 12 liters of water used in 3 days?

Back

The unit rate is 12 liters / 3 days = 4 liters per day.

Front

How do you determine the most convenient spot for calculating unit rate on a graph?

Back

The most convenient spot is often where the line is straight and passes through the origin, making calculations easier.
