question

Solve the inequality and 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.

key idea

To solve for a variable, use inverse operations to undo the operations in the inequality. Be sure to do the same operation to both sides of the inequality.

When graphing an inequality, use a filled-in circle to include a number and an open circle to exclude it.

solution

First, solve for

Subtract 9 from both sides

–

Subtract 9 from both sides

Divide both sides by 8

–

Divide both sides by 8

Now graph the solution. The inequality

–

means that

can be any number greater than

–

Since

cannot be equal to

–

there should be an open circle located on

–

Also, since

can be greater than

–

there should also be an arrow pointing to the right.

So, this is the graph of
