Question

PLEASE ANSWER ASAPwhich scatterplot does NOT suggest a linear relationship between x and y?A) I onlyB) I and ll onlyC) Ill and lV onlyD) I, lll, and IV only

Answer 1

Looking at the graphs, we have the following analysis:

I - The points look like a line, so they suggest a linear relationship.

II - The points also look like a line, so they suggest a linear relationship.

III - The points are very separated, they don't form any pattern, so they don't suggest a linear relationship.

IV - The points go up and then down, suggesting a quadratic relationship (like an arc), so they don't suggest a linear relationship.

Therefore the correct option is C: III and IV only.
