The formula for the slope-intercept form of a line is:
[tex]\begin{gathered} y=mx+b \\ m=slope \\ b=intercept \end{gathered}[/tex]If you have found the slope-intercept form and need to graph the line, but your slope and y-intercept are fractions, you do not really need to make the denominators the same. All you need to do is make a table of values on a range of values from which your graph can be plotted.
