Looking at y=2x-5 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=2 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 2, this means:

rise%2Frun=2%2F1


which shows us that the rise is 2 and the run is 1. This means that to go from point to point, we can go up 2 and over 1



So starting at , go up 2 units


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



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

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

Use slope and y intercept to graph a line. y=2x-5
---
slope = 2
intercept = -5
----
Draw an x/y coordinate system.
Put your pencil point at the y-intercept (0,-5)
----
slope = 2 means "as x increases 1, y increases by 2".
---
So, move your pencil 1 to the right to (1,-5)
then up 2 to (1,-3)
Put a point at (1,-3)
Draw the draph as a line thrm (0,-5) and (1,-3)
