Question

Suppose that y is directly proportional to x and that y=-61 when x=8. Find the constant of proportionality for k.

Answer 1

Can someone help me please

Answer 2

so how would I find outwhat k=

Answer 3

*Thinking*

Answer 4

y = kx

y = -61 and x = 8

Solve for k?

Answer 5

how do I do that do i multiply -61*8

Answer 6

Rearrange the formula first.

y=kx

therefore

k = y/x

k = -61 over 8

Answer 7

k=-61 over8 is that correct is that the end of it

Answer 8

I believe so.

Let me know how it goes =)

Answer 9

correct thanks

Answer 10

;)

Answer 11

Asylum15 I am sorry there is a second question to this problem. use y=kx to find y when x=6

Answer 12

Use Y=KX again.

Now for K use the value you just got, and multiply it by 6
