The answer is C. See, a relief sculpture is a type of technique that gives the impression that the material has been raised above the background plain. The use of the word relief comes from a Latin verb which means "to raise". Hope this helps!

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.
