I'll do the first two to help you get started

#1

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 -1 and the run is 3. This means that to go from point to point, we can go down 1 and over 3

So starting at

, go down 1 unit

and to the right 3 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
