What does it mean for a system of equations to have one solution?

Back

It means the lines intersect at exactly one point.

Front

What does it mean for a system of equations to have no solution?

Back

It means the lines are parallel and never intersect.

What is the y-intercept of a line?

Back

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

Front

How do you find the slope of a line given two points?

Back

Use the formula: (y2 - y1) / (x2 - x1).

What is the significance of parallel lines in a system of equations?

Back

Parallel lines have the same slope and will never intersect, indicating no solution.
