How can we determine inequality using position on a number line?

   Find the number on the other side of the inequality sign from the variable (like the 4 in x > 4).

   Sketch a number line and draw an open circle around that number.

   Fill in the circle if and only if the variable can also equal that number.

   Shade all numbers the variable can be.
