(1) The number of households receiving more than 6 subscriptions a month is closest to x % of 64.
For answering this question, look at the number of points ahead(right) of line depicting 6 subscriptions.
There are 6 dots, so 6 households have more than 6 subscriptions, or 6/64 ~ 10%. x=10%

(2) The slope of the regression line is __ the slope of the dashed line.
A line parallel to x-axis has zero slope, and when both x and y have direct relationship, that is x increases with y, slope is positive, else negative
Regression line: x increase as y increases, thus positive.
Dashed line: y decreases as x increases, thus negative.
Hence, slope of regressed line is more.

(3) The relationship between the number of subscriptions and annual income is ________.
The regressed line gives the relation. It has a positive slop, so positively related.


Hope it helps

Official Explanation

The number of households receiving more than 6 subscriptions a month is about 6, which is closest to 10% of 64.

The answer to the first question is C.

The slope of the regression line is positive and the slope of the dashed line is negative, so the slope of the regression line is greater.

The answer to the second question is B.

As income increases, subscriptions increase, so the relationship between the two is positive.

The answer to the third question is C.
