How do artists use gradation in their work? what does adding value gradation do?

Gradation of color and value can also be useful when painting other subjects. In a still life, for example, you might use a gradation in the background from left to right and from top to bottom. Please give me the brailiest answer?

:) Hoped this helped <3

this is only for with homework. but you can chat with anyone here!

explanation:

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.
