It totally depends on the value of 'a', and if 'a' changes, then (6a-2) immediately changes too. Whatever 'a' is at the moment, (6a-2) is 2 less than 6 times 'a'.
Solution
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the formula for slope

STEP 2: Pick two points
STEP 3: Find the unit price per cup
Since 4 cups cost $5, one cup will cost

Therefore, the answer is $1.25
I don't know if this is right but 0.125
Answer: Choice A) mean, there are no outliers
Have a look at the image attached below. I made two dotplots for the data points. The blue points represent bakery A. The red points represent bakery B. For any bakery, the points are fairly close together. There is no point that is off on its own. So there are no outliers, making the mean a good choice for the center. If there were outliers, then the median is a better choice. The mean is greatly affected by outliers, while the median is not.
