Five Positive Things to Built on in 2021!

i cant think of five things positive however Try to learn from mistakes and just try to have fun the best you can  and everything and try not to think negative all the time :)

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.

i think it's about 10 mins.

actually i think that's wrong, but i don't know how to delete this.

but who knows it might be right.
