What is the graphical representation of a linear equation?

Back

A linear equation is represented graphically as a straight line on a coordinate plane.

What is the point of intersection in a linear system?

Back

The point of intersection is the solution to the system, where the graphs of the equations meet.

What is the elimination method in solving linear systems?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other.

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

Back

A linear system has infinitely many solutions if the equations represent the same line, meaning every point on the line is a solution.

What is a consistent system of equations?

Back

A consistent system has at least one solution, meaning the lines intersect at one point or are the same line.
