Writing Linear Equations When Given Just Two Points

Well, today's plan had to be altered a bit because all of you took more time on the quiz than I had expected (which is, of course, a GREAT thing!). Soooo, instead of working with the handhelds, we will practice writing equations for lines when given just two points on the line. To do this, find the slope, and then plug in the x and y values of one of the points into the equation with the slope to determine the y intercept. Once you have this, you will be able to plug in the values of m and b into the slope-intercept equation. ¡Voila!
