Which scatter plot represents the given data?
x 1|1|2|2|2.5|2.5|4|4|6
y 1.4|8|8.5|8.8|1.5|5.1|3.5|6.3|4

We are given a table of values of these data points as:

  x                y

   1               1.4

   1                 8

   2               8.5  

   2                8.8

   2.5             1.5

   2.5             5.1

    4               3.5

    4               6.3

    6                4  

So, clearly from the data points we could observe that the scatter plot of the following points will contain 2 points at '1' at different distance also 2 data points for '2' one at 8.5 and the other at 8.8. 2 data points at '4'.

Hence, the scatter plot of these data points is attached to the answer.
