Answer 3

Allsia1245 what?

Answer 4

y = k / x

plug in y = 4 and x = 5
and solve for k

Answer 5

4=k/5

Answer 6

solve for k now :)
multiply both sides by 5

Answer 7

Sorry @Novice3000 it was my friend that typed this

Answer 8

k=20?

Answer 9

yes

Answer 10

it's alright lol not mad lol

Answer 11

then y = k / x
plug in the "k"
and keep the y and x
to get the equation

Answer 12

ah so 4=20/5 is the equation for the last one

Answer 13

nope
keep the y and x variables in there
the 4 and 5 were just temporary :)

Answer 14

oh so y=20/x

Answer 15

yes :)

Answer 16

Yes, thank you again :D
