Respuesta :

The phrase y varies directly as x can be understood that y gets bigger when x gets bigger as well, this can be written as,

[tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]

then, using the point (6,48) find the value when x is 2,

[tex]\frac{48}{6}=\frac{y_2}{2}[/tex]

clear for y2,

[tex]y_2=\frac{48}{6}(2)[/tex]

Answer:

[tex]y_=\frac{48}{6}(2)[/tex]
