The graph shown below is a scatter plot with 48 points, each representing the number of radio ads per hour run by a company each day over 48 months, and the corresponding monthly sales revenue that the company earned. The sales revenues, measured in thousands of dollars, were tallied on the last day of each month that the ads were run. The solid line is the regression line, and the dashed line is the line through the points (1, $20,000) and (6, $50,000).
Select the best answer to fill in the blanks in each of the statements below based on the data shown in the graph.
1. The number of months in which the company generated more than $50,000 of revenue is closest to percent of 48.
2. The slope of the regression line is the slope of the dashed line.

1)0, since no month generated revenue > 50000 and only one was able to achieve 50000
2)Slope of regression line is less than the slope of dashed line since slope of regression line is -ve,while slope of dashed line is +ve
3) Relationship is negative since when number of ads increases the revenue decreases

1. zero. There is not a single month when sales revenue crossed 50K.
2.Lesser.
because the regression line is moving downwards (i.e. negative slope) , while the dashed line is moving upward(positive slope).
3.negative
look at the graph, sales revenue is high in the initial months compared to the later. It means they are in inverse relation.
