In this paper, we discuss the existence and uniqueness of points of coincidence and common fixed points for a pair ofself-mappings satisfying some generalized contractive type conditions in $b$-metric spaces endowed with graphs and alteringdistance functions. Finally, some examples are provided to justify the validity of our results.
