Answer:
B. c = fλ
Step-by-step explanation:
The given equation is

To solve for c you must multiply both sides of the equation by lambda.

Answer:

Step-by-step explanation:
First problem. If you want a parallel to a given line, you keep the slope.
Then we use the point-slope form of a line
and we plug in there everything we need.

The second is quite similar. This time we want the perpendicular. It means that the product of the slopes has to be -1.

At this point we have everything, let's replace and write down the line in a better looking form
