If y varies directly as x and y = 4 when x = 2 , find the constant of variation and the value of y when x = 6
[tex]\\[/tex]
Translation: (Direct variation)
y varies directly as x
- y = kx
-------------------------------
- y = 4, x = 2
- 4 = 2k
- 4/2 = k
- 2 = k
----------------------------
- y = ?, x = 6
- y = 2x
- y = 2 · 6
- y = 12

[tex]\color{yellow}\underline\mathbb{ANSWER:}[/tex]
- Constant of variation: 2
- Value of y: 12
