Customers at your store select their groceries from shelves and then pay. Sales records and records of restocks for flaming roast coffee ( 1 lb size) are as follows: # of sales tues 5, we'd 8, thu 2, fri 19, sat 22, sun 15, mon 3, # of restock tue 6, wed 12, thurs 12, fri 18, sat 24, sun 0, mon0. What is the net change of how many bags are on the shelf, from the the beginning of tuesday to the end of monday?

- 2

Step-by-step explanation:

- - - - - - - - - - - T - - W - - TH - - F - - S - - S - - M

# of SALE - - - 5 - - 8 - - - 2 - - 19 - 22 - 15 - - 3

# of restock - 6 - - 12 - - 12 - - 18 - 24 - 0 - - 0

Calculating the change in shelf unit on a daily basis:

Change = difference in restock unit and the unit sold, that is, # RESTOCK - # SOLD

TUESDAY :

6 - 5 = 1

WEDNESDAY :

12 - 8 = 4

THURSDAY :

12 - 2 = 10

FRIDAY :

18 - 19 = - 1

SATURDAY :

24 - 22 = 2

SUNDAY :

0 - 15 = - 15

MONDAY :

0 - 3 = - 3

The net change equals the algebraic sum of all daily changes in shelf unit between Tuesday to Monday ;

[1 + 4 + 10 + (-1) + 2 + (-15) + (-3)]

[1 + 4 + 10 - 1 + 2 - 15 - 3]

[ 1 + 4 + 10 + 2 - 1 - 15 - 3]

= 17 - 19

= - 2

Number of bags decreased by 2

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
