Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.

xy = 7

A. direct variation
B. inverse variation

Respuesta :

[tex]\\ \sf\longmapsto xy=7[/tex]

  • Take x to right and divide

[tex]\\ \sf\longmapsto y=\dfrac{7}{x}[/tex]

Hence

.[tex]\\ \sf\longmapsto y\propto \dfrac{1}{x}[/tex]

Inverse variation
