The required graph is

Step-by-step solution

Step 1. Given information.

Graph each equation by hand by plotting points. Verify your results using a graphing utility.

$y=3x-9$

Step 2. Create table of values.

Start by creating a table of values, we will then use it to plot the points on the graph. select values of x and use the given equation to find the corresponding values of y.

Step 3. Create the graph. 

Plot the points from the table above and connect them with a smooth curve.

Step 4. Conclusion. 

The required graph is
