Next thing I want to do is divide everything by 2, so that I’ll have y all by itself. So the first thing I’m going to do is undo that –x piece by adding x to both sides of the equal sign. What I need to do is get y all by itself. But this one is not quite in y equals mx plus b form yet.
And if this line is in y equals mx plus b form, I can do my 10-second graphing. Here is a problem where I’m asked to graph the equation of the line.
