Question

direct variation equation- y=6 x=-36--- y=-6x, y= 1/6x, y=6x, y=-1/6

Answer 1

\[ \huge\rm y =kx \] equation for direct variation
replace x and y by their values then solve for k

Answer 2

but would it be negative or positive ?

Answer 3

I think it would be 1/6

Answer 4

negative multiply negative = positive
negative divide by negative = positive
negative multiply positive = negative

Answer 5

x = negative 36
so negative divide by positive = negative

Answer 6

the question says -6 and -36

Answer 7

so y = -6 ??
but there is y = 6

Answer 8

oops I wrote it wrong in the first place sorry!

Answer 9

it's okay :-)
so yes k -1/6

Answer 10

not negative that suppose to "=" sign
k = 1/6

Answer 11

thanks can u help me with 2 more?

Answer 12

sure

Answer 13

vaiable y varies directly with variable x and y y =5 x=8 what is the value when y=8

Answer 14

would it be 18?

Answer 15

what is k ??

Answer 16

first step to find k so what's k ?

Answer 17

im confused

Answer 18

again y = kx
equation for direct variation first replace x and y by their values and solve for k

Answer 19

5 times 8

Answer 20

k is multiplying by 8
do cancel out 8 from right side you need to do opposite of multiply which mean divide both side by 8
