The line 1 contains the points (1,1) and (2,4).The line m contains the points (4,1) and (3,-2) investigate if 1 is parallel to m

They are parallel

Step-by-step explanation:

Slope for line 1: (4-1)/(2-1) = 3

Slope for m: (-2-1)/(3-4) = 3

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.
