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.
