graph the equation y-3x=0
put this solution on YOUR website!
Start with the given equation.
Add 3x to both sides.
we can see that the equation is in slope-intercept form
where the slope is
and the y-intercept is
really looks like
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 up 3 and over 1
So starting at
, go up 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
