If /etc/sysctl.conf doesn't exist, where is my sysctl storing configs?

I want to change two values using sysctl. One is the

vm.swappiness=10

and the other,

kernel.sysrq=1

. However, when I run

-p

, it tells me

: cannot open "/etc/sysctl.conf": No such file or directory

, but

-a

returns this . So, I want to ask where is my system storing sysctl config?
