I don't get why students have so much trouble writing equations of lines. It's not just my kids, is it?
Yesterday in Algebra 2 we talked about three forms of a line (slope-intercept, standard, and point-slope). If it were up to me, I'd just do slope-intercept, but standard can be nice when we graph. Especially when it comes to linear programming.
Don't you just love those graphing index cards? I found them at Staples (thanks to @druinok, who posted about them here) and got myself a couple of packs. These are the 3 x 5s, but I also got a pack of 4 x 6s. I'm thinking that these would be something good to use when we get to trig equations in Precalc.
