A line passes through points (2, 1) and (-1, 3). What is the eqaution of this line? A causal relationship means one action or event is the cause of another. A correlational relationship describes a connection between events, but it does not mean one event or action caused the other. Does the video describe a causal or correlational relationship between the health of the Lake Erie ecosystems and human needs and activities surrounding it?

y = 2/-3x + 2 1/3

Step-by-step explanation:

y = mx + b

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.
