Looking at y=7x we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=7 and the y-intercept is b=0 note: y=7x really looks like y=7x%2B0


Since b=0 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
slope=rise%2Frun

Also, because the slope is 7, this means:

rise%2Frun=7%2F1


which shows us that the rise is 7 and the run is 1. This means that to go from point to point, we can go up 7 and over 1



So starting at , go up 7 units


and to the right 1 unit to get to the next point



Now draw a line through these points to graph y=7x

So this is the graph of y=7x through the points and
