Question

Data were gathered and displayed on a scatter plot.

A scatter plot contains the ordered pairs 0,12 and 2,7 and 2,9 and 3,11 and 4,5 and 4,9 and 6,3 and 6,5 and 6,8 and 8,2 and 8,6 and 10,1 and 10,3 and 12,1 and 13,0.

Which of the following is the most appropriate equation to model the data?

ŷ = –10.89x + 0.85
ŷ = –0.85x + 10.89
ŷ = 10.89(0.85)x
ŷ = 0.85(10.89)x

Answer 1

this one and then one more hghh

Answer 2

Oi. Okay working on it

Answer 3

Alrighty depending on how many more we have left it might be better to just randomly guesss for these last couple but let's move through them as quickly as we l can
So we can see that as we move to the right on the x axis, we're moving down on the y one
so as x goes up, y goes down

Answer 4

so we'll need our answer to be negative
so let's cross out the positive choices

Answer 5

that will mean that 10.89 is more likely than 0.85 for b in y=mx+b

Answer 6

y = - (something)x + 10.89
So that'll mean it is B

I am sorry that I wasn't fast

Answer 7

Is there away we can still do the others or no

Answer 8

last one

Answer 9

Alright
