Which line models the data given below?
x y
-2 0
-1 -2
0 -4
6 -16
a. y-2 = -2(x - 1)
b. y-2 =2(x - 1)
c. y + 2 = -2(x + 1)
d. y + 2= 2( x + 1)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

i think that you should ask google for the answer to that problem because if we don't know it google does
