Question

Is the relationship shown by the data linear? If so, model the data with an equation.

Answer 1

moves by 3 and moves by 1 each time; thats consistently linear to me

Answer 2

slope is defined as change in y divided by change in x

y moves -1 for every +3 in x

slope = -1/3

use any point given to define the line using that as a slope

Answer 3

ah i'm still really confused, :/
A. The relationship is not linear.
B. The relationship is linear; y + 5 = (x – 9).
C. The relationship is linear; y – 9 = (x + 5).
D. The relationship is linear; y + 5 = (x – 9).
are my choices, i think its d but not really sure. :|

Answer 4

the relationship is definantly linear

Answer 5

but the slope is not present in the answer choices

Answer 6

option C has the correct point placement .... but lacks the proper slope

Answer 7

thank you, i'd assume this is why i'm struggling with this class. the books are no help.

Answer 8

if those are your options, there is most likely a typo in the book

Answer 9

those are my exact options, it seems like a lot of the questions are missing some type of information which makes it difficult. Then when i think i know what i'm doing, i get the answers wrong on my assignments anyway.

Answer 10

yeah, building confidence starts with having the right options to pick from
