This fugue begins with four entrances, each in a different "voice" (that is, musical line): 0:00 Alto (subject) 0:10 Soprano (answer) 0:19 Bass (subject) 0:28 Tenor (answer) Which best describes the texture of this excerpt?

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.

i dont know, i dont live in japan sorry though
