Question 931376: How do I graph the inequalities: x- y > 8
I don't know what the slope is. Is 8 the y intercept
Answer by Fombitz(32388)   (Show Source):
You can put this solution on YOUR website! First graph the line 
Here the slope is  and the y-intercept is  .
So one point is (0,-8).
Since the slope is 1, change in y over change in x is one.
So to get another point add (1,1) to the intercept.
(0,-8)+(1,1)=(1,-7)
Now that you have two points, you can plot the line.
OK, so now pick a point not on the line. (0,0) is convenient.
Test the inequality.
If the inequality is true, shade the region containing (0,0).
If the inequality is false, shade the region that doesn't contain (0,0).
False, so shade the region not containing (0,0).
