Front

What does it mean for two equations to have infinite solutions?

Back

It means that the equations represent the same line in the graph.

Front

What is substitution in solving systems of equations?

Back

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

Front

How do you check if a solution (x, y) is correct for a system of equations?

Back

Substitute the values of x and y into both equations to see if they hold true.

Front

What is the graphical representation of a system of equations with no solution?

Back

The lines representing the equations are parallel and never intersect.
