Answer #1

1.

a. The answer is option C. See the attached picture below.

2.

a. Note that the only option which contains (1,4) is option 3. Hence, this is the scatter plot

b. The answer in the picture is correct

c. You can draw many lines through the points to show that there is a linear relationship. For example, try connecting the leftmost point to the rightmost point. This could be one linear approximation.
