@jhonyy9

Answer 23

lets take the first one as example...

1.2 = (1.2)*1
2.4 = (1.2)*2
3.6=(1.2)*3

here y=k*x where the constant k=1.2... hence option A has direct variation...

can you try the remaining ones and let me know ?

Answer 24

sup jhonyy

Answer 25

the all are devided the same

Answer 26

?????

Answer 27

option B does not have direct variation... can you tell me why ??

Answer 28

its what i got on the question

Answer 29

lets look at option B:

if it had direct variation y=k*x

15=(3)*5 => k=3
30=(3)*10 => k=3
60=(4)*15 => k=4

as the value of k is different for one of the pairs... the table does not have direct variation...

Now can you try the same with remaining options ??
