Ratio Tables & Graphing

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 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 a missing value in a ratio table?

Back

To find a missing value, use the known ratios to set up a proportion and solve for the unknown.

Front

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).

Front

What does the x-coordinate represent?

Back

The x-coordinate represents the horizontal position on a graph.

Front

What does the y-coordinate represent?

Back

The y-coordinate represents the vertical position on a graph.

Front

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 vertically to the y-coordinate.

Front

What is the relationship between ratios and proportions?

Back

Ratios compare two quantities, while proportions state that two ratios are equal.

Front

What is the slope of a line in a graph?

Back

The slope of a line indicates its steepness and direction, calculated as the rise over run (change in y over change in x).

Front

How can you determine if two ratios are equivalent?

Back

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