How do you graph the inequality #y<2#?

The inequalities are great talkers I think. It says "Every value smaller than #2# in #y#-axis".

It doesn't tell anything about #x#-axis, so it is indifferent to #x#. Every #x# value will be accepted.

Finally, since it doesn't include #y=2# the border of the form should be dashed. Dashed lines tell the reader that the value is not included.

So draw a parallel line to #x#-axis from #y=2# point #(0,2)#. (The line should be dashed). And shade the area of the coordinate plane which #y# values are smaller than #2#.

Result:

graph{y<2 [-10, 10, -5, 5]}
