Question 7.
From the given graph, let's explain what the sloe number means in terms of cable tv subscribers.
From question 6, we have the slope:
m = 1.3
Using the points:
(x1, y1) ==> (0, 10.8)
(x2, y2) ==> (4, 16)
The points are from the year: 1976 and 1980
This slope here means that the number of cable tv subscribers between 1976 and 1980 increases by 1.3 million subsribers a year.
ANSWER:
The slope 1.3 means that the number of cable tv subscirbers between 1976 and 1980 increases by 1.3 million subscribers each year.
