What is t, and t+1?

I know that y= -4x +k

and perpendicular to that would be y=(1/4)x+k

but where should i go from there?

The perpendicular is y = (1/4)x, not (1/4)x + k. Find the x solution for the intersection as a function of k i.e. x = x(k). Same with the y solution y = y(k). Then find what k satisfies y(k) - x(k) = 1. Then evaluate x(k) to get t.
