Question 133256
Graph the inequality of x+y >8 I know how to plot the points and test for the shading. I'm just having trouble with setting up the x and y table. 
----------------------
The table is for the boundary of the inequality, not for the inequality.
The boundary is x+y = 8
Solve for y: y = -x+8
--------------------------
If x = 0, y = 8
If x = 1, y = 7
If x = 2, y = 6 
etc.
----------------
Now graph the boundary as a dashed line since it is not part of the solution.
{{{graph(400,300,-10,10,-10,10,-x+8)}}}
--------------------------
Then shade the area ABOVE the boundary since you want y to GREATER than
the boundary value.
