1. The problem asks to mark all the relative minimum points on the given graph. 2. A relative minimum point on a graph is a point where the function changes from decreasing to increasing, creating a "valley". 3. From the description, the graph starts below $y=-4$ at $x=-7$, increases upwards, passes through the x-axis near $x=0.9$, peaks between $y=7$ and $y=8$ at about $x=2$, then descends through $y=1$ at about $x=6$, and rises slightly after $x=6$. 4. The relative minimum points occur where the graph changes from decreasing to increasing. 5. Observing the description, the graph is increasing from $x=-7$ to the peak at $x=2$, so no minimum there. 6. After the peak at $x=2$, the graph descends until about $x=6$, then rises again after $x=6$. 7. Therefore, the relative minimum point is near $x=6$, where the graph changes from decreasing to increasing. 8. The approximate coordinates of the relative minimum point are $(6,1)$. Final answer: The relative minimum point is at approximately $\boxed{(6,1)}$.
