Lesson 1-3 Graphs of Equivalent Ratios

Front

What is an equivalent ratio?

Back

An equivalent ratio is a ratio that expresses the same relationship between two quantities, even if the numbers are different. For example, 2:1 and 4:2 are equivalent ratios.

Front

How do you find a missing value in a ratio?

Back

To find a missing value in a ratio, you can set up a proportion and cross-multiply to solve for the unknown.

Front

What does the point (6,12) represent in a graph of equivalent ratios?

Back

The point (6,12) represents that for every 6 hours, $12 is given, showing the relationship between hours and money.

Front

What is the purpose of a ratio table?

Back

A ratio table is used to organize equivalent ratios and helps in identifying patterns and relationships between quantities.

Front

How can you determine the ratio from a graph?

Back

You can determine the ratio from a graph by identifying the change in the y-value compared to the change in the x-value.

Front

What is the significance of the slope in a graph of equivalent ratios?

Back

The slope represents the rate of change between the two quantities, indicating how much one quantity increases for a unit increase in the other.

Front

If a graph shows a line, what does it indicate about the ratios?

Back

A straight line indicates that the ratios are equivalent and consistent across the values plotted.

Front

What is the ratio of 8 to 2?

Back

The ratio of 8 to 2 is 4:1.

Front

How do you read coordinates on a graph?

Back

Coordinates are read as (x,y), where 'x' is the horizontal position and 'y' is the vertical position.

Front

What does the term 'proportion' mean in mathematics?

Back

A proportion is an equation that states that two ratios are equal.
