Question

suppose y varies directly as x. write a direct variation equation that relates x any. y=6 when x=9

Answer 1

What are the answer choices?

Answer 2

How do you do this?

Answer 3

No answer choice

Answer 4

Ok, how?

Answer 5

Thats also not an equation.

Answer 6

Direct variation equation in this case would be \[\LARGE y=kx\]
We are given values to plug in and solve for k so:
\[\LARGE 6=9k\]
Now just solve:
\[\LARGE \frac{2}{3}=k\]
Final equation:
\[\LARGE y=\frac{2}{3}x\]

Answer 7

What does k equal?

Answer 8

K is just a constant

Answer 9

Read through the explanation..

Answer 10

K is there because of why though?

Answer 11
