To have a parallel line, your slope must be equal in both the line you are trying to create and the line that you originally have. So, in this problem that should be a dead give away.

b?

directrix · Answer

I agree - just use the y = mx + b form where m is the slope and b is the y-intercept. That is, use that after getting m, the slope, according to @blehbleh .

yes b is correct. nice job
