We know, any point which lies on the \\\\(y\\\\)-axis will be of the form \\\\((0,y)\\\\), where \\\\(y\\\\) is any real number.Here, the points \\\\((0,4)\\\\) and \\\\((0,-8)\\\\) are of the form \\\\((0,y)\\\\), where \\\\(y=4\\\\) and \\\\(-8\\\\), respectively.Therefore, options \\\\(B\\\\) and \\\\(D\\\\) is correct.
