Front

What does it mean if two lines are parallel?

Back

They have the same slope and will never intersect, meaning there is no solution.

Front

What does it mean if a system has infinitely many solutions?

Back

The equations represent the same line, so every point on the line is a solution.

Front

How do you graph a linear equation?

Back

You can plot points that satisfy the equation and connect them to form a line.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.

Front

What is the x-intercept of a line?

Back

The point where the line crosses the x-axis.
