y=mx+b. b is the y-intercept while m is slope. So to graph using slope-intercept form you put in the slope for m and the intercept for b. So if the equation is y= ½ x+2. ½ is the slope and 2 is the y-intercept. When you graph the equation you put the first point at 2 on the y-axis then you move 1 up then 2 to the right and keep doing that.
