Work Step by Step

To solve -$\frac{1}{3}$x$\lt$2, isolate x. To do this, divide -$\frac{1}{3}$ on each side of the inequality. It then becomes x$\gt$-6. Notice that the sign changed to "greater than" because we divided each side by a negative number. To graph, place an open circle on -6 because the answer doesn't includes the value -6 (you also know to not shade it because the inequality only has the "greater than" symbol). Then, shade right of the -6 because the other values for x are greater than -6.
