-12 x + 3y > 9
__________________________
An example of inequality in a system with infinite solutions (the region between the two lines have infinite solutions )
_______________________
Please, give me some minutes to take over your question
______________________________________
-12 x + 3y > 9 We can draw this inequality
3y > 12 x + 9
y > 12/3 x + 9/3
y > 4x +3 (we are interested in the region above the line and we have a dotted line because we do not include the line just y > 4x +3)
the line y = 4x + 3
x y point
0 3 (0,3)
1 7 (1,7)
-1 -1 (-1, -1)
