Question

Find the missing term in the table where constant of proportionality is -8.

• A. -56

Answer 1

The correct option is A -56
Given constant of proportionality = -8

$⟹\frac{y}{x}=\frac{-8}{1}$

At x = 7

$⟹\frac{y}{7}=\frac{-8}{1}$

$⟹y=-8\times 7$

$⟹y=-56$

Therefore, at depth 7 yd, the temperature is -56°C.
