Answer:
y = - 4.4
Step-by-step explanation:
from the question
y = -6.6
x = 9.9
y∝ x
y = kx ..... where k is introduced as a constant of proportionality
solve for k
y=-6.6 and x = 9.9
we have,
-6.6 = k × 9.9
-6.6 = 9.9k
divide both sides by 9.9
-6.6/ 9.9 = 9.9k/9.9
-0.667= k
therefore k = - 0.667
now, find y when x = 6.6
from the equation y = kx
y = -0.667 × 6.6
y = - 4.4
