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]\\[/tex]

[tex]\color{yellow}\underline\mathbb{ANSWER:}[/tex]

  • Constant of variation: 2
  • Value of y: 12
