The following tables each show the inventory of a warehouse and the number of orders for four different products which have been shipped out to customers.Which table best represents a linear relationship?
Accepted Solution
A:
Orders: x Inventory: y
1) First table x2-x1=6-3→x2-x1=3 y2-y1=1920-1960→y2-y1=-40
x3-x2=9-6→x3-x2=3=x2-x1 y3-y2=1900-1920→y3-y2=-20 different to y2-y1=-40. The table does not represent a linear relationship.
2) Second table x2-x1=7-5→x2-x1=2 y2-y1=1860-1900→y2-y1=-40
