Looking at y=%285%2F2%29x%2B1 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=5%2F2 and the y-intercept is b=1


Since b=1 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 5%2F2, this means:

rise%2Frun=5%2F2


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



So starting at , go up 5 units


and to the right 2 units to get to the next point



Now draw a line through these points to graph y=%285%2F2%29x%2B1

So this is the graph of y=%285%2F2%29x%2B1 through the points and
