If you were writing a Classical style aria in the key of G major, which pitches would you use most prominently? Why?

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.

the correct answer is the first option. the principle of design that suggests a structural relationship between different elements within a work of art is unity.  unity is the principle of the quality of cohesiveness that is expressed with compositional similarity, oneness and cohesion.
