Question 617633
how to draw a graph of equations
x-y>0
----
1st: Solve for "y":
y < x
2nd: Graph the boundary (y = x) as a dashed line.
---
3rd: Since you want y to be Less than x, shade
the half-plane BELOW the boundary.
==============================================
x+y>0
1st: Solve for y:
y > -x
2nd: Graph the boundary (y = -x) as a dashed line.
3rd Since you wan y to be GREATER tan -x, shade
the half-plane ABOVE the boundary.
