A rating of good or excellent indicates the audience liked the movie, while a rating of poor indicates the audience disliked the movie.
<h3>How to determine the rating of the film from the 46–55 age group?</h3>A movie producer accomplished a survey behind a preview screening of her latest movie to estimate how the film would be accepted by viewers from various age groups. The table displays the numbers of viewers in various age groups who ranked the film excellent, good, average, and poor.

The slope of the best fit for the 3 given points is 500, so the correct option is b.
<h3>How to find the slope?</h3>
Remember that for a line that passes through two points (x₁, y₁) and (x₂, y₂) the slope is:
With the 3 given points we can find 3 slopes, and then we will need to find the average of these 3.
The 3 points are: (3, 2,750), (6, 4,200), and (9,5,750)
Then the 3 slopes are:
The average slope is:
So the correct option is b.
