For equations below, which method is easier to use? Why?

• Graphing, because both are already in y = mx + b form. Also, substitution, because one equation is already solved for y. 

• Elimination, because both are already in ax + by = c form. 

• Elimination, because both are already in ax + by = c form. Also, graphing, because both are already in y = mx + b form. 

• None.
