You can put this solution on YOUR website! .............(1)
...............(2)
__________________________________solve both for
.............(1)
...............(2)
graph the first inequality:
.............(1)
you need two points to draw a graph:
if then ; so, first point is ( , )
if then => => => ; so, second point is ( , )
since we have >=, line is part of solution
so, shade a part above a line; that is solution
graph second inequality on the same graph
...............(2)
if then ; so,we take first point is ( , )
if then ; so, second point is ( , )
since given that is less then-our line is not part of solution and need to be dashed line (I can't do it here)
now shade solution part
finally, we can shade solution to the system:
