Looking at y=%281%2F4%29x-4 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=1%2F4 and the y-intercept is b=-4


Since b=-4 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 1%2F4, this means:

rise%2Frun=1%2F4


which shows us that the rise is 1 and the run is 4. This means that to go from point to point, we can go up 1 and over 4



So starting at , go up 1 unit


and to the right 4 units to get to the next point



Now draw a line through these points to graph y=%281%2F4%29x-4

So this is the graph of y=%281%2F4%29x-4 through the points and

how do i graph the line y=(1/4)x-4

Plot a couple of points and draw a line thru them.
---
If x = 0, y = -4 giving you point (0,-4)
---
If x = 4, y = 1-4 = -3 giving you point (4,-3)
