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.
[tex]y = kx[/tex]
Putting y=2 and x = -12
[tex]2 = -12k\\k = \frac{2}{-12}\\k =-\frac{1}{6}[/tex]
So the equation will be:
[tex]y = -\frac{1}{6}x[/tex]
Putting x = -0.3
[tex]y = -\frac{1}{6} *-0.3\\y =0.05[/tex]
Hence,
y = 0.05 when x = -0.3
