Contrafacts. A contrafact is a song that uses a new melody over an already existing chord progression. They exist because of quirk in US copyright law. You can copyright lyrics and the melody, but you can't copyright titles and the chord progression.

Explanation:

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.

ive noticed that too but is this a question
