Answer:
The quadrilateral formed is a trapezoid
Step-by-step explanation:
In this case, it is necessary to know what points A, B, C, and D.
If the points are equal to the following coordinate points
A (-2, 1)
B (2, 1)
C (3, -2)
D (-3, -2)
As shown in the image the answer would be a trapezoid.
________________________________
The figure cannot be a square, a rhombus or a rectangle since by definition these are:
A square has all sides of equal length and all its right angles.
A rhombus is a parallelogram that has all sides of equal length and all its angles different from right angles.
A rectangle is a parallelogram that has all its right angles.
The figure that we obtain is neither a parallelogram nor does it have all its right angles.

Answer:
y = -4x + 60
Step-by-step explanation:
(0, 60) and (4,44)
Slope:
m=(y2-y1)/(x2-x1)
m=(44 - 60)/(4-0)
m= (-16)/4
m= -4
Slope-intercept:
y - y1 = m(x - x1)
y - 60 = -4(x - 0)
y - 60 = -4x
y = -4x + 60
