Constructing Scatterplots — Quiz

Question 7 • Mathematics 8

When a scatterplot is created from a table of values, which statement is correct?

Answer
A
It is possible for two points to have the same x -coordinate, but it is impossible for them to have the same y -coordinate.
B
It is possible for two points to have the same y -coordinate, but it is impossible for them to have the same x -coordinate.
C
It is possible for two points to have the same x -coordinate and the same y -coordinate.
D
It is impossible for two points to have the same x -coordinate or the same y -coordinate.

Explanation

Each row in the table gives an ordered pair, (x, y), to plot. Different rows can have the same x-value and the same y-value, so their points land in the exact same location on the scatterplot; therefore, it is possible for two points to share both coordinates. Choice C is correct.
