Throughout history, architects have always addressed and integrated three key issues; , and

satin. 

"very shiny satin may look great in the fabric store or in the sewing room, but once onstage it can look fake and cheap as it reflects the light from the fixtures."

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.
