By linear inequality in one variable, do you mean something like

#x <= 5#

or

#y > 2#

If yes, just draw your line and shade the entire area that satisfies your inequality

For example, in #x <= 5#,
we should draw a vertical line at #x = 5# and shade the entire area to its left (since #<=#)

For y > 2, we should draw a broken horizontal line (since #>#, not #>=#) at y = 2 and shade the entire area above it
