Unit 2 Introducing Proportional Relationships

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other quantity is constant.

Front

How can you identify a proportional relationship on a graph?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

What is the equation of a proportional relationship?

Back

Front

If Andre rode his bike at a constant speed of 1 mile in 5 minutes, what is the equation for time in terms of distance?

Back

Front

What does the slope of a line in a proportional relationship represent?

Back

The slope represents the constant of proportionality, which indicates how much one quantity changes in relation to another.

Front

In a recipe, if 3 tablespoons of oil are used for every 2 tablespoons of vinegar, what is the ratio of oil to vinegar?

Back

The ratio of oil to vinegar is 3:2.

Front

What does it mean if a point lies on the line of a graph representing a proportional relationship?

Back

It means that the quantities represented by that point maintain the same ratio as defined by the proportional relationship.

Front

How do you determine which container is filling more quickly from a graph?

Back

The container that has a steeper slope on the graph is filling more quickly.

Front

What is the vertical axis typically labeled in a graph representing a recipe with oil and vinegar?

Back

The vertical axis is labeled 'Oil (tablespoons)'.

Front

What is the horizontal axis typically labeled in a graph representing a recipe with oil and vinegar?

Back

The horizontal axis is labeled 'Vinegar (tablespoons)'.
