Pianists began abandon stride-influenced playing partly because the recently established allowed for time keeping to be done on that instrument instead of the left hand of the piano.

Unrelenting walking bassline

Explanation: Pianists began abandon stride-influenced playing partly because the recently established unrelenting walking bassline allowed for time keeping to be done on that instrument instead of the left hand of the piano.

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.
