I believe the correct answer is a hope this helps
(-1,-9) because if we substituted 1 into x y would be 9 and if we substituted 1/2 into x y would be 3 but if we substituted -1 into x y would be 1/9 so therefore that value is incorrect
No they are not! If you multiply 3/4 times 4 to get the denominator as 12, you would get 9/12 which is not equivalent
