A language is a structured system of communication used by humans, including speech (spoken language), gestures (sign language) and writing. Most languages have a writing system composed of glyphs to inscribe the original sound or gesture and its meaning. The scientific study of language is called linguistics.

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.
