Ratio Tables, Equivalent Ratios, and Graphs

Front

What is a ratio?

Back

A ratio is a comparison of two quantities, showing the relative size of one quantity to another.

Front

How can ratios be expressed?

Back

Ratios can be expressed in three ways: as a fraction, with a colon (e.g., 3:2), or in words (e.g., '3 to 2').

Front

What does it mean for two ratios to be equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities, meaning they simplify to the same fraction.

Front

How do you simplify a ratio?

Back

To simplify a ratio, divide both terms by their greatest common divisor (GCD).

Front

What is a ratio table?

Back

A ratio table is a table that displays pairs of numbers that form equivalent ratios.

Front

How do you find equivalent ratios using a ratio table?

Back

You can find equivalent ratios by multiplying or dividing both terms of a ratio by the same non-zero number.

Front

What is an ordered pair in a graph?

Back

An ordered pair is a pair of numbers used to locate a point on a graph, typically written in the form (x, y).

Front

How do you plot a point on a graph?

Back

To plot a point (x, y), move x units along the horizontal axis (x-axis) and y units along the vertical axis (y-axis).

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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