Looking at y=%288%2F5%29x%2B5 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=8%2F5 and the y-intercept is b=5


Since b=5 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 8%2F5, this means:

rise%2Frun=8%2F5


which shows us that the rise is 8 and the run is 5. This means that to go from point to point, we can go up 8 and over 5



So starting at , go up 8 units


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



Now draw a line through these points to graph y=%288%2F5%29x%2B5

So this is the graph of y=%288%2F5%29x%2B5 through the points and

The equation to the straight line is y+=%288%2F5%29x+%2B+5.
This means the slope is 8%2F5 and y-intercept is +5.

Hence, first select the point (0,5) on the y-axis. This is point A.
Next, go 5 units right (positive x direction) and 8 units up (positive y direction). This is point B.
Join these two points and extend on both sides you will get your line.
