Looking at y=%289%2F5%29x%2B2 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=9%2F5 and the y-intercept is b=2


Since b=2 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 9%2F5, this means:

rise%2Frun=9%2F5


which shows us that the rise is 9 and the run is 5. This means that to go from point to point, we can go up 9 and over 5



So starting at , go up 9 units


and to the right 5 units to get to the next point



Now draw a line through these points to graph y=%289%2F5%29x%2B2

So this is the graph of y=%289%2F5%29x%2B2 through the points and
