Looking at y=%282%2F5%29x-3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=2%2F5 and the y-intercept is b=-3


Since b=-3 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 2%2F5, this means:

rise%2Frun=2%2F5


which shows us that the rise is 2 and the run is 5. This means that to go from point to point, we can go up 2 and over 5



So starting at , go up 2 units


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



Now draw a line through these points to graph y=%282%2F5%29x-3

So this is the graph of y=%282%2F5%29x-3 through the points and

graph y=2/5x-3
---------------
Plot two points:
If x = 0, y = -3
If x = 5, = -1
-------------------
Plot (0,-3), and (5,-1)
and draw a line thru them.
