Question

I need to know how to do this. who is wrong? and why?

Answer 1

Answer: Joseph is right

Explanation:

First find out what point x is, which is located at (-1,-7). Then according to the rule (x,y) -> (y,-x), it becomes (-7, 1). This means Tara is wrong. Now we can look at what quadrant (-7,1) is in, or the second quadrant. This means Joseph is right.
