Between which x-values and y-values does the cluster in this scatter plot lie 30 points

The green circle shows the cluster. This is where most of the data tends to stay. The smallest x-value is 4 (shown by the vertical pink line) and the largest x-value is 6 (shown by the vertical blue line). As for the y-value: the smallest is shown by the horizontal pink line at 6 and the largest is 9 shown by the horizontal blue line. This means the answer is C.

Hope this helped :)

The answer is C because i took the test in edmentum and got it right
