5.4 Graphing Ratios

Front

What is a ratio?

Back

A ratio is a comparison of two quantities, showing how many times one value contains or is contained within the other.

Front

How do you write a ratio?

Back

Ratios can be written in three ways: as a fraction (1/2), with a colon (1:2), or with the word 'to' (1 to 2).

Front

What does it mean to graph a ratio?

Back

Graphing a ratio involves plotting points on a coordinate plane that represent the relationship between two quantities.

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 find the ordered pair for a point on a graph?

Back

To find the ordered pair, identify the x-coordinate (horizontal position) and the y-coordinate (vertical position) of the point.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a graph where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a graph where the x-coordinate is zero.

Front

How do you complete a ratio table?

Back

To complete a ratio table, you fill in the missing values by maintaining the same ratio between the quantities.

Front

What is the purpose of a graph in representing ratios?

Back

Graphs visually represent the relationship between two quantities, making it easier to see trends and patterns.

Front

What does it mean for two ratios to be equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities, even if the numbers are different.
