Answer:
Graph has been shown in the attached file.
Step-by-step explanation:
We have to graph the linear equation 
We can graph this by table method. Let us make a table by taking some random values of x and find the corresponding y values.

On simplifying this equation, we get

Now, we make a table for x and y values. Then we plot the points in the xy-plane and then join them to get the graph.
The table and the graph of the equation is shown in the attachments.
