Answer:
Trapezoid
Step-by-step explanation:
Given quadrilateral has vertices at points A(-2,-1), B(3,13), C(15,5) and D(13,-11).
Find slopes of lines AD and BC:

Since the slopes are the same, lines AD and BC are parallel.
Find slopes of lines ABD and CD:

Since the slopes are different, lines AB and CD are not parallel.
This means quadrilateral ABCD is trapezoid (two opposite sides - parallel and two another opposite sides - not parallel)
Answer:
-1/5 or - .2
Step-by-step explanation:
4x(2+8)= -8
(4*-.2)(2+8)= -8
-.8(2+8)= -8
-.8(10)= -8
-8=-8
<u>Answer:</u>
The correct answer option is D. (-2, 1).
<u>Step-by-step explanation:</u>
We are given the coordinates of the square A"B"C"D" after the rule is applied and we are to find the coordinates of the vertex A.
For that, we will reverse the rule.
A" = (-5, -3)
x: - 5 + 4 = -1
y: - 3 + 1 = -2
Now we will reverse the 90 degrees counter in counter clockwise rotation:
(x, y) ---> (y, -x)
(-1. -2) ---> (-2, -(-1)) = (-2, 1)
