Given the linear circuit above, it is known that when a $1.5 k\Omega$ load is connected to the terminals $A$ and $B$, the load current coming out of terminal $A$ is 11 mA. If a $7.5 k\Omega$ load is connected to the terminals, the load current is 3 mA. The open circuit voltage, $V_{oc}$, is defined with the + terminal at A.

Find the Thevenin equivalent circuit parameters:
$R_{th} =$ $k\Omega$
$V_{oc} =$ $V$

Find the current, $I_{load}$, in a $15 k\Omega$ load.
$I_{load} =$ $mA$
