Question

does the data in the table represent a linear function? if so, wirte a rule for the function.

(below is what the table looks like)
x | -2| -1| 0 | 1| 2|
y | -7| 1| 8 | 17| 25|

answer choices
yes; y = 8x +9
yes; y = 8x + 8
no
yes; y = 1/8x + 8

Answer 1

what is (25-17)/(2-1) ?
8

what is
(1 - -7) /( -1 - -2) ?
8/1 = 8

humm looks like slope = 8 so far

but what about
(17 -8)/ (1 - 0) = 9 !!!!!
oh my, not the same slope
crash
not on a straight line of constant slope

Answer 2

Please have patience, child.

Answer 3

I did. It is not a straight line.
answer is no

Answer 4

so the answer is no??

Answer 5

Sorry I didn't see that he answered. thank u

Answer 6

It is almost a linear function, if the 8 becomes a 9, i.e. the y-values become
-7,1,9,17,25.

Otherwise the answer is no.

Answer 7

You are welcome.

Answer 8

It is no for connexus, I checked it as of 2023.

#1 = 2

#2 = the / dash, flat line, another /, not sure how to explain the photo better than that

#3 = the graph that crosses the y line with 2, points on the line being (1,-1), (-1, 5), and (2,-4)

#4 = no

#5 = y = 2x - 6


* * * sorry if 2 & 3 are unclear, if it helps, the letter options I got were both D.


I hope this helps!!!
