Answer:
A. 15
Explanation:
the initial statement is
y ∝ x
to convert to an equation multiply by k the constant of variation
⇒ y = k x
to find k use the given condition
y = - 24 when x = 8
y = kx ⇒ k = y - 24
_ = _ = - 3
x 8
equation is

Y = 3x
−−−−−−−−−−−−−−
when x = 10 then
y = −3×10 = − 30
30 ÷ 2 = 15
