How do you graph #x>=2#?
By graph, I'm assuming you mean in a line graph, apologies if I'm wrong.
A neat trick in determining which direction the line should point, look at the inequality sign in equations similar to this. Think of the inequality as an arrow, if it points right, draw the line on the graph pointing right, if left, then left. Make sure you make a filled in circle on the dot at the number 2 because the inequality equation means,
x is greater or equal to 2.
