Will give brainliest to whoever gets it right the coordinates of the vertices of quadrilateral abcd are a(−4, −1) , b(−1, 2) , c(5, 1) , and d(1, −3) . drag and drop the choices into each box to correctly complete the sentences.

A(−4, −1) , B(−1, 2)

Slope AB = (2 + 1)/(-1 + 4)

Slope AB = 3/3

Slope AB = 1

B(−1, 2) , C(5, 1)

Slope BC = (2 - 1)/(-1 - 5)

Slope BC = -1/6

C(5, 1) , and D(1, −3)

Slope CD = (1 + 3)/(5 - 1)

Slope CD = 4/4

Slope CD = 1

A(−4, −1) and D(1, −3)

Slope AD = (-1 + 3)/(-4 - 1)

Slope AD = -2/5

AB and CD has same slope and equal 1

So AB and CD are parallel

Answer

Slope AB = 1, Slope BC = -1/6, Slope CD = 1 and Slope AD = -2/5

Quadrilateral ABCD is not a parallelogram because only one pair of opposite sides is parallel .

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
