One way is to first isolate y

Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is

Since this tells us that the y-intercept is

.Remember the y-intercept is the point where the graph intersects with the y-axis

So we have one point

Now since the slope is comprised of the "rise" over the "run" this means

Also, because the slope is , this means:

which shows us that the rise is -3 and the run is 2. This means that to go from point to point, we can go down 3 and over 2

So starting at

, go down 3 units

and to the right 2 units to get to the next point

Now draw a line through these points to graph

So this is the graph of through the points

and
