If the value of "y" varies directly with "x"
and y = -1 when x = 3, find "y" if x = 9.
enter the number that belongs in the green box.
y = [? ]

y = - 3

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 1 when x = 3, then

k = = - , thus

y = - x ← is the equation of variation

When x = 9, then

y = - × 9 = - 3
