Answer:
Step-by-step explanation:
The y-intercept is where the line itersects the y-axis, which is the dark vertical line. This is -8 represented as the constant in the equation.
To find the slope, find the rise over run. Every time the line goes over 1 it goes down 6, so the slope would be -6.
The question should result in data with the greatest variability is "How many customers used each of the bank’s 20 ATM machines last week? and is denoted as option B.
<h3>
What is Variability?</h3>
This is defined as the extent to which a data or point is spread out and how far apart they lie.
It is characterized by a large number of variables which in this case is getting data from 20 ATMs for seven days. This would result in more values being gotten and is therefore the most appropriate choice for the question with the most variability.
