Answer:
The equations that are equal to 15-8y=-11 are...
- Number 1
- Number 4
The answer to the question is (-3,3)
Answer: y = 36x
Step-by-step explanation: Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x = , y = 12, then
k = = = 12 × 3 = 36
y = 36x ← equation of variation
