The last two classes we discussed solving systems by graphing and substituion. Today I gave Ben some problems that had him decipher when to use which method. We discussed how when equations are in slope intercept form or standard form, graphing is a decent approach to take. However if the variables are rearranged some other way, or if one variable is already solved for, then substitution would be the best approach. Ben worked at the white board graphing the equations. We saw situations where the graph ended up being the same line (one on top of the other), so we acknowledged there would be infinitely many solutions. Ben seems to prefer graphing over substition. I think it's because he's had more practice with it.
