Fine Art and Commercial photography have little in common.
True
False

False.

Explanation:

While Fine Art and Commercial photography are two very different types of photography, the lines between them are constantly being blurred. Especially nowadays with modern technology, the distinction is a slim one. They have many things in common (especially because Fine Art covers so many types of subjects and styles) even as they are different.

Also, I just took the test and got it right haha.  

that is good that you know it

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.
