What does the slope represent in a graph?

Back

The slope represents the rate of change between the two variables in a proportional relationship.

Front

In the equation y = mx, what does 'm' stand for?

Back

'm' represents the slope of the line.

Front

How do you find the slope from a graph?

Back

The slope can be found by taking the rise (change in y) over the run (change in x).

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value of the ratio between two proportional quantities.

Front

If a graph passes through the origin, what does that indicate?

Back

It indicates that the relationship is proportional.
