Answer:
Positive; more fruit bars are sold as the temperature rises;
Two bars for every 1 °F
Step-by-step explanation:
I plotted a scatter chart in Excel and asked it to draw the regression line and include the equation for the line of best fit
The graph has a positive slope, so a positive correlation exists between the temperature and the number of fruit bars sold.
The real-world meaning of the positive slope of the line of best fit is that more fruit bars are sold as the temperature rises.
The equation for the line of best fit is
y = 2.1855x - 101.02
There are approximately two more fruit bars sold for every 1 °F the temperature rises.

The answer is choice (B).
A standard quadratic written in vertex form is:
y = (x - h)^2 + k, where h and k are the x and y coordinates of the vertex.
So, if h is negative (in this case, -3), then it becomes x + 3.
If k is negative, though, (in this case, -5) then it becomes (x + 3)^2 - 5.
Therefore, the answer is (B).
