Answer:
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 that y = - 1 when x = 3, thus
- 1 = 3k ( divide both sides by 3 )
- = k
y = - x ← equation of variation
When x = 9, then
y = - × 9 = - 3
