Question

POINTS AND POINTS AND POINTS. ANSWER ONLY IF U TOOK THE TEST ON K12 AND POST PICTURE OF CORRECT ANSWERS.

The coordinates of the vertices of quadrilateral ABCD are A(−1, −1), B(−3, 3), C(1, 5), and D(5, 2). Drag and drop the choices into each box to correctly complete the sentences. The slope of AB⎯⎯⎯⎯⎯ is Response area, the slope of BC⎯⎯⎯⎯⎯ is Response area, the slope of CD⎯⎯⎯⎯⎯⎯ is Response area, and the slope of AD⎯⎯⎯⎯⎯ is Response area. Quadrilateral ABCD is Response area because Response area.

Answer 1

slope of AB: -2

slope of BC: 1/2

slope of CD: -3/4

slope of AD: 1/2

Quadrilateral ABCD is a trapezoid because there is one pair of parallel sides.

Explanation:

I solved for the slopes using slope formula. Also, I determined that the quadrilateral was a trapezoid since there was at least one pair of parallel sides. I'm sorry that I don't have a k12 account, but I hope this helps.

Answer 2

AB=-2

BC=1\2

CD=-3\4

AD=1\2

Explanation:

The slope of AB is - 2,

Slope of BC is

Slope of CD is

Slope of AD is ,

ABCD is trapezoid because one pair of opposite sides is parallel.
