To determine the type of correlation shown in a scatter graph, you would typically look at the pattern of the plotted points. If the points trend upwards from left to right, it indicates a positive correlation. Conversely, if the points trend downwards, it suggests a negative correlation. If the points are scattered without any discernible pattern, it indicates little to no correlation.

A scatter graph - unless the relationship is exact. If so, use a line (which need not be a straight line).
It depends on the range of ages, but a moderate positive correlation.

You plot your data as points on a Cartesian coordinate system (X/Y graph). You chose "Scatter" from the chart type in your spreadsheet program.
"If y tends to increase as x increases, then the data have a positive correlation. If y tends to decrease as x increases, then the data have a negative correlation. If the points show no correlation, then the data have approximately no correlation."

I suggest a scatter-graph of line graph, with time as the independent axis.
