Front

What is a Proportional Relationship?

Back

A relationship where the ratio of inputs to outputs is constant.

Front

What does a positive slope indicate on a graph?

Back

It indicates that as one variable increases, the other variable also increases.

Front

What can be said about the slopes of similar triangles?

Back

The slopes of corresponding sides of similar triangles are the same.

Front

How is the constant of proportionality (k) represented in the equation?

Back

Front

What is the relationship between the slopes of the hypotenuses of similar triangles?

Back

The slope of the hypotenuse of one triangle is the same as the slope of the hypotenuse of the other triangle.

Front

What is the definition of slope in a coordinate plane?

Back

Slope is the ratio of the change in y to the change in x between two points on a line.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope.

Front

What does it mean if a line has a negative slope?

Back

It means that as one variable increases, the other variable decreases.

Front

What is the formula for calculating slope?

Back

Front

What is a Nonproportional Relationship?

Back

A relationship where the ratio of inputs to outputs is not constant.
