Relations and Inverse Functions

So I am trying to study notes and do homework for my math class. We are studying Relations and Inverse functions. I know how to go from a Relation to a Inverse function and when i am given the domain and range I can graphg. I do not know how to find my own domain and range to graph my relation. My homework problems are telling me I need to take the relation and turn it into a Inverse function and graph both. How do I find the ordered pairs to graph? One of the first problems says y=3-7x. Please help me understand how to graph this. Also the Inverse function I got was x= (3-7)/7

So what do I plug in when it comes to the Inverse Function 3-y over 7?

Hi Samantha,
 
You have quite a bit of freedom.
 
You can pick values that do not make the denominator of a fraction 0. 
 
Often people will pick numbers near 0 like -2,-1,0,1,2 , but it is up to you.
 
Let me know if this helpful.
 
Best regards?
