Graphing Ratio Relationships (Lesson 1-3 and 1-4)

Front

What is a ratio?

Back

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as 'a to b' or a:b.

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 does it mean for a ratio to be in simplest form?

Back

A ratio is in simplest form when the two numbers have no common factors other than 1, meaning they cannot be reduced further.

Front

If 1 scoop of coffee grounds requires 2 cups of water, how many cups of water are needed for 3 scoops?

Back

6 cups of water.

Front

What is the X-axis in a coordinate plane?

Back

The X-axis is the horizontal axis of the coordinate plane, where values are plotted left to right.

Front

What is the Y-axis in a coordinate plane?

Back

The Y-axis is the vertical axis of the coordinate plane, where values are plotted up and down.

Front

How do you find the total amount using a ratio?

Back

To find the total amount using a ratio, multiply each part of the ratio by the same number to scale it up or down.

Front

What does the point (1, 75) represent in a graph of a ratio?

Back

It represents that for every 1 hour traveled, 75 miles are covered.

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.

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something (e.g., miles per hour).
