----
You only need 2 points to graph a line.
----
x + y = 6
Let x = 0, then y = 6, giving you (0,6)
Let y = 9, then x = 6, giving you (6,0)
Plot those 2 points and draw a line thru them:

============================================
x-y = 4
Let x = 0, then y = -4, giving you (0,-4)
Let y = 0, then x = 4, giving you (4,0)
Plot those and draw a line.
