I just found it easier to plug x=0 into those equations and a few seconds of mental arithmetic tells me answer (b) is the right one.

That's the trouble with these multiple choice questions. They are often simplest to solve with trial by error.

You could just skip the first step and since you know that the point (0, 6) falls on the line, you can plug in 0 as x and see which evaluates to 6

No need to work out the vertex for this one... only one gives the correct y-int....
