Plug it in when using points to find the equation of a line. Two sets of points can only mean one thing, the slope formula. Have your learners start by finding the slope and then plugging that slope and one of the points into slope intercept form. Solve for b and voila! they have all the information they need to write the equation of the line. The video does three examples, one including a fraction as the y-intercept.
