Question

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

Answer 1

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]}
