This smart notebook lesson introduces graphing lines using the slope and y-intercept. There are 16 total practice problems. The first few involve graphing with a table of values. The next few involve graphing by stating and using the slope and y-intercept. I have my students write the slope as a fraction with directions (ex: up or down/right or left) for each question when they are first learning this concept. I would print out the slides and have your students do the same. There are also some word problems from which the students must write y = mx + b equations. This is an introduction lesson so all of the equations are already in y = mx + b form. This lesson would be ideal for a quick review in 9th grade Algebra or an introduction for first time 8th graders who have never graphed a line using the slope and y-intercept.
