The equations represent the same line.

Front

What is the graphical representation of a system of equations?

Back

The intersection points of the lines representing the equations.

Front

What is the slope of a line?

Back

The ratio of the rise over the run between two points on the line.

Front

How can you determine if two lines are parallel from their equations?

Back

If they have the same slope.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.
