Jerome is writing a coordinate proof to show that the midsegment of a trapezoid is parallel to its bases. He starts by assigning

Bingel [31]

Answer:

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

$(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

The midpoint of the line segment NK is given by

$(\frac{0+2b}{2},\frac{0+2c}{2})$

∴R(b,c)

The slope of the line joining the points (x₁,y₁) and (x₂,y₂) is given by

$m =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Slope of RS is

$m_{RS} =\frac{c-c}{a+d-b} = 0$

Hence

coordinates of R(b,c)

and slope of NM is 0.
