Just replace the x in the question with -2, and the y with 2.
Therefore, you're doing ((-2)(2²))/7 which is -2 times 2 squared all over 7.
-2 × 2² = -8
-8/7 is your answer.
You will basically want to plug -2 into x and 2 into y.
Making the equation (-2(2)^2)/7
2^2 is 4 so the equation is then (-2(4))/7
Which then simplifies to -8/7
