Respuesta :
solve for y because x is the independent variable...
9x+3y=12 divide the entire equation by 3
3x+y=4 subtract 3x from both sides
y=-3x+4
9x+3y=12 divide the entire equation by 3
3x+y=4 subtract 3x from both sides
y=-3x+4
The equation as a function is [tex]f(x) = - 3x + 4[/tex]
The equation of the function is given as:
[tex]9x + 3y = 12[/tex]
Subtract 9x from both sides of the equations
[tex]3y = 12 - 9x[/tex]
Rewrite the equation as:
[tex]3y = - 9x + 12[/tex]
Divide through by 3
[tex]y = - 3x + 4[/tex]
Express y as a function of x
[tex]f(x) = - 3x + 4[/tex]
Hence, the equation as a function is [tex]f(x) = - 3x + 4[/tex]
