Which sketch shows the inverse of y=a x where a is greater than 1?

The answer would be a line that is not as steep and a reflection in the line y = x.

If the a value in the equation is greater than 1, we will have a line that is steeper than the line y = x.  

Now, we we take the inverse of the line, it will have a slope that is lower than y = x.

The graphs will be reflected in the line y = x.

Try graphing y = 3x and 3y = x.

The answer is a. yes, it asks a question that can be answered correctly (by measuring hands).
