What does the slope (m) represent in a linear equation?

Back

The rate of change of y with respect to x.

Front

How can you determine if two lines are parallel?

Back

If they have the same slope and different y-intercepts.

Front

What does it mean if two lines are the same line?

Back

They have the same slope and y-intercept.
