Front

What is a proportional relationship?

Back

A relationship where the ratio between two variables is constant.

Front

What does it mean if a graph passes through the origin?

Back

It indicates that the relationship is proportional.

Front

What is the slope of a proportional relationship?

Back

The slope is the constant rate of change between the two variables.

Front

How do you identify a proportional graph?

Back

Look for a straight line that passes through the origin.

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.
