Which equation represents a direct variation
o y = 2
o y = x + 4
o y = 2x
o y = 2/3
save and exit
mark this and return

y = 2x.

Step-by-step explanation:

Direct variation is given by  y = kx where k is a constant.

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.

ou would have 12 of each
