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

Back

It means that the equations represent parallel lines that never intersect.

What does it mean for a system of equations to have infinitely many solutions?

Back

It means that the equations represent the same line, resulting in an infinite number of intersection points.

How do you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into each equation; if both equations are satisfied, the point is a solution.

Front

What is the graphical representation of a system of equations?

Back

The graphical representation consists of lines or curves plotted on a coordinate plane, where intersections represent solutions.
