You've heard of "greater than" and "less than", right? Terrific! First we'll express inequalities on a number line and then write them using information in word problems.
Practice telling whether or not a value solves an inequality.
We've been taking a lot of equalities. What about when the relationships between numbers need to be expressed as inequalities? For example, less/greater than and/or equal to? How can we represent that idea on a number line?
We're plotting a simple inequality on a number line in this example.
Practice writing equations of inequalities graphed on number lines. Identify number line graphs of inequalities.
Practice writing inequalities with variables to describe real-world situations.
