Question

Look at the following function:

x y
–3 –8
–2 –6
–1 –4
0 0


Matt said that the function is linear.

Justine said that the function is nonlinear.

Which of the following explains who is correct? (1 point)


Matt, because for every 1-unit increase in x, there is an increase in y by 2
Matt, because for every 2-unit increase in x, there is an increase in y by 1
Justine, because the point (–3, –8) does not lie on the straight line that contains the other points
Justine, because the point (0, 0) does not lie on the straight line that contains the other points

Answer 1

Oneeee moreeeeee pleaseeeeee my answer was the Third one

Answer 2

im poretty sure its C

Answer 3

Yeaa i was thinking that too

Answer 4

Is my question right? my answer was C @Directrix

Answer 5

I mean my answer

Answer 6

I think that option C is not correct. I wish you two would have given a reason as to why you chose C.

Answer 7

Its C bro lol, the pattern is messed up :P

Answer 8

lol, the pattern is messed up --> What does that mean?

The slope of the line on which (-3,-8) and (-2,-6) is the same as the slope of the line on which the points (-2,-6) and (-1,-4) lie. I don't see anything messed up about that.

Answer 9

this aint my question lol u aint needa question me... Hold up u may have changed my mind, the pattern isnt messed up, i was just thinking of timing everything by 2... But A and B cant be right because it says the # increases, but the #s are negative, and D cant be right because (0,0) has nun to do with the problem

Answer 10

Look at the graph. It is not (-3, -8) that is off the line.

It is (0,0)

Answer 11

Oh wait i was reading the graph from bottom to top... yeah ur right, its A

Answer 12

>this aint my question lol u aint needa question me...

Mathematics is all about why something is true.
You made a statement and I asked why.
That is natural in mathematics.

Answer 13

Oh wait... its D

Answer 16

im changing my answer too much xD

Answer 17

im 100% its D tho

Answer 18

Look at the graph I posted.

D) Justine, because the point (0, 0) does not lie on the straight line that contains the other points

Answer 19

yeah, sorry Samirah xD

Answer 20

Well thank you guys you really know your stuff :)

Answer 22

You are welcome from both of us.

Answer 23

Soooo the answer is D right just making sure?

Answer 24

D) Justine, because the point (0, 0) does not lie on the straight line that contains the other points

Answer 25

Directrix: "Why do you think the answer is D?"

Answer 26

It messed up the pattern.

Answer 27

i know im joking with u, i just took ur own words from ur mouth :P
