Graph the solution.

To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

When graphing an inequality on a number line, you need to choose between using a filled-in circle or an open circle.

Use a filled-in circle when an inequality shows ≤ or ≥. For example, this number line shows

≥

Use an open circle when an inequality shows < or >. For example, this number line shows

Use inverse operations to solve for

Since this inequality includes multiplying by

you should divide by 3 on both sides to find the solution.

Now, graph the solution on the number line. The inequality

means that

can be any number less than 2, but it cannot be equal to 2.

So, draw an open circle on 2. Then, draw an arrow pointing toward the numbers less than 2, which are to the left.
