Unit Rates from Ordered Pairs, Tables and Graphs

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 much of one quantity corresponds to one unit of another quantity.

Front

How do you calculate a unit rate?

Back

To calculate a unit rate, divide the quantity of one item by the quantity of another item, ensuring the denominator is 1.

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

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position of a point on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position of a point on the coordinate plane.

Front

How can you find the unit rate from a table?

Back

To find the unit rate from a table, look for the ratio of the quantities and simplify it to see how much of one quantity corresponds to one unit of the other.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the unit rate that describes the relationship between two proportional quantities.

Front

How do you represent a unit rate in an equation?

Back

A unit rate can be represented in an equation in the form y = kx, where k is the unit rate.

Front

What is the significance of the slope in a graph?

Back

The slope of a graph represents the unit rate, showing how much y changes for a change in x.
