In this smartboard lesson, students will review how to graph lines from an equation in y=mx+b, or slope-intercept form. First students will review how to graph a line using a table by substituting in values. Then, they will practice graphing a line by first identifying the y-intercept and then using the slope to graph several more points. A real-life application problem is also included, as well as examples where either the y-intercept or slope is zero.
