Answer 2

any thoughts?

Answer 3

i think its A

Answer 4

there is no real indication that the points in the second graph are appreciably different

Answer 5

lol^^ and im not sure what u mean @amistre64

Answer 6

there is no way to determine what the graph will do since the extra points are basically in line with the points already established.

Answer 7

ohhh okay so it would be D then because it will shift up considerably

Answer 8

your responses are not suggesting that you have any idea what im talking about ...

Answer 9

i understand what ur saying.. its a guess

Answer 10

its a guess yes, but some guesses are better than others :)


draw a line of best fit on the second dataset, does it seem significantly different from whats already on the first set?

Answer 11

yeah they kinda look the same or line up the same way

Answer 12

ive drawn an almost exact replica of the first line ...

Answer 13

both sets are so close that the combined data set is not in anyway a significant change from whats already there.

Answer 14

so it will just remain the same then

Answer 15

now whatever 'slightly' means cannot be defined by the problem. id say they would remain the same instead of trying to see how 'slight' of a change there is.

not saying its right, but i dont see another approach

Answer 16

oh okay .. it makes more sense that way i understand where ur coming from

Answer 17

good luck :)

Answer 18
