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 ...

x \neq 5 \) reads as ‘\(x\) is not equal to 5.’ Show the inequality \(x \textless 2\) on a number line. \(x\) is less than (<) 2, which means an open circle at 2 must be used. \(x\) is less ...
