The answer is a: Dry media

Dry media is a media that consists of natural or synthetic mineral or plant substances that deposit crystalline or splinter-like fragments in the paper fibers.

Explanation:

Dry media includes drawing materials such as charcoal, pastel, chalk and so on. These materials can be applied easily to any surface and they can also be easily erased or blended. Charcoal is the oldest material among the materials because it was common in every fire place.

coordinates of r(b,c)

slope of nm is 0.

step-by-step explanation:

the midpoint of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

the midpoint of the line segment nk is given by

∴r(b,c)

the slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

slope of rs is

hence

coordinates of r(b,c)

and slope of nm is 0.
