Given the data set:
(x, y)==> {(1960,3), (1970,3.5), (1980, 5), (1990,6)}
To plot the data above, the x-corrdinates: (1960; 1970; 1980; 1990) which are the first values will be on the horizontal axis, while the y-coordinates (3, 3.5, 5, 6), will be on the vertical axis.
Thus, the correct scatter plot for the data set above will be Scatter Plot A.
The graphical representation is below
