Question

Hey there Ms or Mr could you please help me out? Just a heads up this isn't a quiz it's my homework assignment for today, it's about Properties of quadrilaterals.

Answer 1

The coordinate of L is (-6, 1).

The coordinate of N is (1, 8).

`\begin{gathered} \text{Given two points P(x}_1,y_1)andQ(x_2,y_2),thecoordinateofthemidpoint,(x_m,y_m)\text{ of the } \\ \text{ line joining PQ is given by: } \\ x_m=(x_1+x_2)/(2),\text{ y}_m=\frac{y_1_{}+y_2_{}}{2}, \end{gathered}`

Therefore,

in our case

`(x_m,y_m)=((-6+1)/(2),(1+8)/(2))=(-2(1)/(2),4(1)/(2))`

Correct choice is D
