Which pair of points has a negative slope?
a) (-3,,-8)
b) (-3,,17)
c) (4,,-10)
d) (4,,-4)

Option A is the right answer.

Step-by-step explanation:

The slope is given by :

Putting the values in the formula :

Option A:

= -5 (negative)

Option B :

(positive)

Option C:

= 6 (positive)

Option D:

= 3 (positive)

Option A is the right answer.

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.
