For what value of $k$ does the line represented by the equation $1-kx = -3y$ contain the point $(4,-3)$?

1 - kx  =  - 3y         sub (4, -3) into the equation

 

1 - k(4) = - 3(-3)     simplify

 

1 - 4k  =  9       subtract 1 from both sides

 

-4k  =  8         divide both sides by - 4

 

k  =  -2
