Answer Choice $G$: $(1,1)$

Work Step by Step

The question said that the relation was not a function. That means there will have to be two points with the same $x$-coordinate (Since the relation has to fail the vertical line test.) The x-coordinate has to either be $-3$,$-2$, $1$, or $1.5$ to satisfy the condition that there are two points that have the same $x$-coordinate. The only answer choice with an $x$-coordinate of any of those is $(1,1)$.
