Front

What does it mean when two lines are on top of each other?

Back

The lines are coincident, meaning they have infinitely many solutions as they represent the same line.

Front

What is the solution to a system of equations?

Back

It's the ordered pair (x, y) that makes both equations true.

Front

What is a system of equations with one solution?

Back

A system has one solution when two lines intersect at exactly one point.

Front

What does it mean when two lines intersect?

Back

It means that the system of equations has one unique solution.

Front

What is the ordered pair that represents the solution to the system?

Back

The ordered pair (1, 3) is the solution to the system.

Front

What is a system of equations with no solution?

Back

A system has no solution when the lines are parallel and never intersect.

Front

What is a system of equations with infinitely many solutions?

Back

A system has infinitely many solutions when the lines are coincident (on top of each other).

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis.
