What point would you have when (-7, 3) is reflected over the line y=x? A. (3,-7)
B. (-3,7)
C. (7,-3)
D. (-7,3)

I believe it’s C.
The line y=x looks like a even, diagonal line going through (0, 0) on a graph. If you have (-7,3) , your in the first quadrant (in the upper left square of the graph). If you reflect it diagonally, the digits themselves would remain that same, but the value would flip (if it’s positive, it’ll become negative, if it’s negative, it’ll become positive). So if we do that with (-7, 3), it becomes (7, -3).
Solution: (7, -3)
