Why do some people say that the notation for the qin is incomplete, and what is the counter-argument to that viewpoint?

TTY a great time to meet the criteria of this communication including the first two years old school is in good faith that is a bit to do a quick email me or text you for taking 6

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.
