it’s a positive correlation because it’s moving upwards.

as the number of gold medals increase, the number of silver medals increase because you can clearly see that happening on the graph.

a reasonable number of silver medals won by a county who won 8 gold medals would also probably be around 8 because the correlation is positive, so it needs to move upwards.

a reasonable number of silver medals won by a county who won 13 gold medals would also probably be around 13 because the correlation is positive, so it needs to move upwards.
