Question 923946: graph a line with identical slope and y intercept
slope -5 and y intercept (0,8)

You can put this solution on YOUR website!
This is the equation y = -5x + 8

Looking at y=-5x%2B8 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-5 and the y-intercept is b=8


Since b=8 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, this means:

rise%2Frun=-5%2F1


which shows us that the rise is -5 and the run is 1. This means that to go from point to point, we can go down 5 and over 1



So starting at , go down 5 units


and to the right 1 unit to get to the next point



Now draw a line through these points to graph y=-5x%2B8

So this is the graph of y=-5x%2B8 through the points and
