Answer:
The type of function the equation represents is "directly proportional" ⇒ B
Step-by-step explanation:
- The equation of the directly proportional is y = kx, where k is the constant of proportionality, k is a real number that could be positive or negative
- The equation of the inversely proportional is xy = k or y =
, where k is the constant of proportionality, k is a real number that could be positive or negative
Let us solve the question using the rules above
∵ The equation of the function is y = -8x
→ Compare it with the two forms above
∵ The equation is in the form of y = kx, where k = -8
∴ The equation represents directly proportional
∴ The type of function the equation represents is "directly proportional"
