Abstract : In this paper we show that if $\Cal K$ is an incline with multiplicative identity and $I$ is an $r$-ideal of $\Cal K$ containing a unit $u$, then $I=\Cal K$. Moreover, we show that in a non-zero incline $\Cal K$ with multiplicative identity and zero element, every proper $r$-ideal in $\Cal K$ is contained in a maximal $r$-ideal of $\Cal K$.
