Write the equation in general form ax + by + c =0.

1/2 y - 1/3 x - 1 = 0

2x -3y +6 =0

Step-by-step explanation:

1/2 y - 1/3 x - 1 = 0

Multiply by 6 to clear the denominators

6*(1/2 y - 1/3 x - 1) = 0*6

3y -2x-6=0

Multiply by -1 because we want x to be positive

-1(3y -2x-6)=0*-1

-3y +2x +6 = 0

Rearrange

2x -3y +6 =0

This is in the general form

f(x) = y

f(-3) = -5
