Students address the slant of a graphed line in the following lesson; the slant is most commonly referred to as "slope". They begin by learning that the slope is the relationship between the rise and the run of a given line, and they use the slope formula to calculate the slope between two ordered pairs on a graph. I have provided a number of practice problems, including answers for student convenience in checking their work. Students are introduced to the four types of slope, and they learn to recognize these four types readily. At the conclusion of the lesson, they will be walked through a "real life" situation and calculate the constant rise of a roller coaster track, given specific "run" distances; they then predict the elevation of the track at a given distance from where the track elevation initiates. Have an outstanding day as you teach your students all about the slope of a line! .
