the table represents the population of a country during the years 1984-2006. if x represents the number of years after 1984, the line-of-best fit is

y = 29.2x + 24363

Step-by-step explanation:

X = number of years after 1984 ;

X:

0

3

10

17

22

Y:

25000

25077

22257

25437

25565

Using the online linear regression calculator, the line of best fit obtained after preparing the model parameters is ŷ = 29.2075X + 24363.44197

Approximately;

y = 29.2x + 24363

With :

y being the population value

x = number of years after 1984

Slope = 29.2

Intercept = 24363

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
