Since given equation is a straight line you only need two points to graph it. You already have one point, the y-intercept=-4 and the slope is 1/3. To find the second point, start from -4 on the y-axis then move one unit up and 3 units to the right (rise/run). As a check, plug in a number like 3 and see if y falls on the line you just drew. To graph a line it is just as easy in most cases to plot points, but learning this method will get you to better understand what a straight line is and hopefully makes algebra more interesting.
