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, representing the values of the variables that satisfy all equations.

How do you determine if a system of equations has no solution?

Back

A system has no solution if the equations represent parallel lines, which never intersect.

What is the substitution method in solving linear systems?

Back

The substitution method involves solving one equation for one variable and substituting that expression into the other equation.

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 is a consistent system of equations?

Back

A consistent system has at least one solution, meaning the equations intersect at one or more points.

What is an inconsistent system of equations?

Back

An inconsistent system has no solutions, meaning the equations represent parallel lines.
