B, A, and C

Explanation:

There's no way for me to answer this tbh, it's very self explanatory.

They were made of animal hide for practical and ceremonial purposes depending on what the animal was.

Many symmetrical designs of geometric shapes and simple lines represented symbols or pictures, usually symbolizing respect, honor, strength, etc.

This is my whole explanation, I also took the test. Have a great day. <3

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.
