What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

What is the solution to a system of equations?

Back

The point where the graphs of the equations intersect, representing the values of the variables that satisfy all equations.

How do you determine if a system of equations has one solution?

Back

If the lines intersect at exactly one point, the system has one solution.

What is the substitution method in solving systems of equations?

Back

A method where one equation is solved for one variable, and that expression is substituted into the other equation.

What is the elimination method in solving systems of equations?

Back

A method where equations are added or subtracted to eliminate one variable, making it easier to solve for the other.

Front

What does it mean if two equations are dependent?

Back

The equations represent the same line, leading to infinitely many solutions.

Front

What does it mean if two equations are independent?

Back

The equations represent different lines, leading to exactly one solution.
