What? Direct Variation?

Results from yesterday's test were shared with the class. We then talked about a special case of the slope-intercept form of a linear equation where b = 0. All of these equations will produce lines that pass through the origin. These are called direct variations. The equations for these lines look like this: y = mx. Another way to write this equation is y/x = m, where m is a constant value (the slope). Students caught on to this very quickly.
