Step-by-step explanation:
Since, y varies inversely as x.

Haha, you first start off with adding 3 to both sides, cancelling the -3, and adding it to 9. you end up with 5x=12, in which you divide both sides by 5. you get 2 and 2/5 or 12/5! hope that helps :)
Answer:
The reflection image of (5, -3) across the line y = -x is (3, -5).
Step-by-step explanation:
You can find the reflection equation by putting the value of x and y in the line given one by one.
