Answer 1

Answer: Choice B

Reason

We apply a 90 degree counter-clockwise rotation first, and then a reflection over the x axis.

The rotation rule we use is
`(x,y) \to (-y,x)`

The reflection rule to use is
`(x,y) \to (x,-y)`

The order is important because the order is right to left. It's similar to how f(g(x)) has g(x) evaluated first and then f(x) next. This will mean choice A has the order reversed and we can eliminate it.

I used GeoGebra to confirm the answer is correct.
