A health food store has launched a new pack of vitamins for children. The store records the number of packs ordered by a random
sample of 100 online customers and the number of packs ordered by a random sample of 100 walk-in customers.
Which of the following inferences can be drawn about the buying pattern of the online customers versus that of the walk-in customers?
Online customers buy an average of five packs compared with walk-in customers, who buy an average of three packs.
Online customers buy an average of five packs compared with walk-in customers, who buy an average of two packs.
Online customers buy an average of six packs compared with walk-in customers, who buy an average of three packs.

Part A)
Given
- Slope m = 6
- Point (7, 2)
Using the point-slope form of the line equation
where
m is the slope of the line
(x₁, y₁) is the point
In our case:
- m = 6
- (x₁, y₁) = (7, 2)
substituting the values m = 6 and the point (x₁, y₁) = (7, 2) in the point-slope form of the line equation
Therefore, the equation in point-slope form for the line having the slope m = 6 and containing the points (7,2) will be:
Part B)
Given
- Slope m = -3
- Point (3, 8)
Using the point-slope form of the line equation
where
m is the slope of the line
(x₁, y₁) is the point
In our case:
- m = -3
- (x₁, y₁) = (3, 8)
substituting the values m = -3 and the point (x₁, y₁) = (3, 8) in the point-slope form of the line equation
Therefore, the equation in point-slope form for the line having the slope m = -3 and containing the points (3, 8) will be:
