How do you solve and graph #-8r < 16 #?
The inequality sign in the middle changes when you multiply or divide an inequality by a negative number, so we'll need to make the r term positive.
This will appear as an open circle on -2 (since -2 is not included in the solution) and a line drawn to the right on a number line graph.
The desired area is shaded to the RIGHT of the dotted vertical line on the Cartesian plane at x=-2.

To solve and graph the inequality -8r < 16:
-
Divide both sides by -8 (note: when dividing or multiplying an inequality by a negative number, flip the inequality sign): r > -2
-
Graph the solution on a number line, indicating that r is greater than -2 but does not include -2. This is represented by an open circle on -2 and an arrow to the right.
The graph visually represents the solution to the inequality -8r < 16.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
