What is a ratio table?

Back

A ratio table is a table that displays pairs of numbers that form a ratio, helping to visualize the relationship between the quantities.

How do you find missing values in a ratio table?

Back

To find missing values, use the known ratios to set up equivalent fractions or proportions.

What are coordinates in a graph?

Back

Coordinates are a set of values that show an exact position on a graph, typically written as (x, y).

What does the x-axis represent in a graph?

Back

The x-axis is the horizontal line in a graph that typically represents the independent variable.

What does the y-axis represent in a graph?

Back

The y-axis is the vertical line in a graph that typically represents the dependent variable.

How do you plot a point on a graph?

Back

To plot a point, start at the origin (0,0), move along the x-axis to the x-coordinate, and then move up or down to the y-coordinate.

Front

What is the purpose of graphing a ratio table?

Back

Graphing a ratio table helps visualize the relationship between the two quantities and can reveal patterns or trends.

Front

What is a proportional relationship?

Back

A proportional relationship is when two quantities maintain a constant ratio or rate.

Front

How can you determine if two ratios are equivalent?

Back

Two ratios are equivalent if they can be simplified to the same fraction or if their cross products are equal.
