Start with the given equation.
Add to both sides.
Rearrange the terms.
Divide both sides by to isolate y.
Reduce.
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 -3 and the run is 1. This means that to go from point to point, we can go down 3 and over 1
So starting at , go down 3 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
