Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.

Answer:

y is directly proportional to x

y=kx, where k is a constant

Now, y=12 when x=15

[tex]12 = k \times 15 \\ k = \frac{12}{15} \\ \boxed{k = 0.8}[/tex]

When x=2,

[tex]y = 0.8 \times 2 \\ \boxed{y = 1.6}[/tex]

Equation: y=kx

y: 1.6
