Question

For the direct variation, find the constant of variation. Then find the value of y when x = −0.3.

Answer 1

y = 0.05 when x = -0.3

Step-by-step explanation:

The direct variation between y and x is denoted as:

y∝x

when the proportionality symbol is removed, the constant of proportionality is introduced.

$y = kx$

Putting y=2 and x = -12

$2 = -12k\\k = \frac{2}{-12}\\k =-\frac{1}{6}$

So the equation will be:

$y = -\frac{1}{6}x$

Putting x = -0.3

$y = -\frac{1}{6} *-0.3\\y =0.05$

Hence,

y = 0.05 when x = -0.3
