Is this relationship proportional? (0,0) (2,4) (4,8) (6,12) Why?

Is this relationship proportional?
(0,1) (2,5) (3,9) (4,10)
Why?​

Since the value of y is always the double of x, the relationship (0,0) (2,4) (4,8) (6,12) can be considered proportional.

Since the division of y by x gives different values, the relationship (0,1) (2,5) (3,9) (4,10) is not proportional.

Step-by-step explanation:

A relationship (x,y) can be considered proportional if the division of x by y is always the same.

Is this relationship proportional? (0,0) (2,4) (4,8) (6,12)

Why?

The double of 0 is 0

The double of 2 is 4.

The double of 4 is 8

The double of 6 is 12.

Since the value of y is always the double of x, the relationship (0,0) (2,4) (4,8) (6,12) can be considered proportional.

Is this relationship proportional? (0,1) (2,5) (3,9) (4,10)

Why?​

Here, we cannot estabilish a relation, which means that they are not proportional.

Since the division of y by x gives different values, the relationship (0,1) (2,5) (3,9) (4,10) is not proportional.

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.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
