Question

It is given that y is directly proportional to x. What is the constant of variation?

Answer 1

Answer:

The constant of variation is -4

Step-by-step explanation:

If y is directly proprtional to x, then we write:

$y \propto \: x$

If we introduce the constant of proportionality or variation k, then we obtain:

$y = kx$

When x=1, y=-4 (We can choose any ordered pair from the table)

$- 4 = k(1)$

$k = - 4$

Therefore the constant of variation is -4.
