10. Determine the most precise name for the quadrilateral & find the area. (2 points) A(3,4) B(8,1) C(2,-9) D(-3,-6)

Rectangle

Step-by-step explanation:

Slope of line = change in y ÷ change in x

Slope of line AB =

Slope of line BC =

Slope of line DC =

Slope of line AD =

As slope of AB = slope of DC ⇒ AB is parallel to DC

As slope of BC = slope of AD ⇒ BC is parallel to AD

As the slope of AB (and DC) is perpendicular to BC (AD) then all interior angles = 90°

Therefore, quadrilateral is a rectangle.
