y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k =
=
= - 
hence y = -
x
when x = 9, then
y = -
× 9 = - 3
Answer: The answer is the square root of 5.

Answer:

Step-by-step explanation:
<em>Time</em><em> </em>is the dependent variable, so you set your function equal to <em>s</em>. Then, the correlation of the graph has a
