Looking at we can see that the equation is in slope-intercept form where the slope is and the y-intercept is note: really looks like

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 9 and the run is 1. This means that to go from point to point, we can go up 9 and over 1

So starting at , go up 9 units

and to the right 1 unit 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
