Ratio Tables, Equivalent Ratios, and Graphs

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

What is an equivalent ratio?

Back

Equivalent ratios are ratios that express the same relationship between two quantities, even if the numbers are different.

Front

How do you create a ratio table?

Back

A ratio table is created by listing pairs of equivalent ratios in a table format, showing how one quantity changes in relation to another.

Front

What is the purpose of a coordinate plane?

Back

A coordinate plane is used to graph points, lines, and curves, allowing for the visualization of relationships between two variables.

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What are the coordinates of the origin on a coordinate plane?

Back

The coordinates of the origin are (0,0).

Front

How do you find equivalent ratios?

Back

To find equivalent ratios, you can multiply or divide both terms of the ratio by the same non-zero number.

Front

What does the x-axis represent in a coordinate plane?

Back

The x-axis represents the horizontal line in a coordinate plane, where the y-coordinate is zero.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical line in a coordinate plane, where the x-coordinate is zero.

Front

How can you determine the slope of a line from a graph?

Back

The slope of a line can be determined by calculating the rise over run, which is the change in y divided by the change in x.
