300
In a system of equations, this is the best method to use when one of the equations is already solved for one of the variables. Graphing or substitution?
What is the substitution method.
300
A system will have this many solutions if the equations have the same slope but different y-intercepts.
What is no solution (or 0) looks like two parallel lines
