It helps further cement new concepts by allowing students to describe these items in their own words. It encourages logical thinking by forcing students to organize their thoughts. It also helps them learn how to tell a story, communicate ideas and record important moments.

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.

what are the choices?
