Looking at y=x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=1 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 1, this means:

rise%2Frun=1%2F1


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



So starting at , go up 1 unit


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



Now draw a line through these points to graph y=x%2B3

So this is the graph of y=x%2B3 through the points and

Graph the equation and identify the y-intercept
y=x+3
-------------------------
To graph the equation you need two points:
Let x = 0, then y = 3; point (0,3)
Let y = 0; then x = -3; point (-3,0)
-----------------
Plot the tow points and draw a line thru them.
The y-intercept is (0,3)
