Show the inequality \(y \textless 2\) on a number line. \(y\) is less than (<) 2, which means an open circle at 2 must be used. \(y\) is less than 2, so an arrow below the values of 2 must be ...

Do you know what a circle looks like? Can you name some other shapes too? A two dimensional (2D) shape is made of lines. Sometimes the lines are curved and sometimes the lines are straight.
