Question 520712
y=6 is a line parallel to the x axis intercepting the y axis at 6

2x-2y=-4
/2
x-y=-2

Generate values for y from values of x	
Assume any three or more values for x and plug in the equation.
				
x	0	-3	3	6	
y=	2	-1	5	8	
(x,y)	(0,2)	(-3,-1)	(3,5)	(6,8)	

plot the points and draw the line
