Okay so I had a question in TBR that said to choose the graph that shows the relationship between the *magnitude* of the following formula

U = - GMm/r

I see that the slope is y = 1/x and thus inversely proportional. However, doesn't the negative sign mean the graph is flipped? The answer in TBR is the standard inverse proportionality curve. Thanks
 
The answer (reflected inverse graph) to that question in TBR is what you're referring to – choice D.
