We have to identify the quadrilateral with no line of symmetry and have rotational symmetry.
Line of symmetry is the imaginary line which divide the given quadrilateral in two equal halves.
Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.
Parallelogram is a quadrilateral which has no line of symmetry as we can not draw any imaginary line which divides the parallelogram in two equal halves.
But Parallelogram has rotational symmetry as when a parallelogram is rotated around a center point (turned) a number of degrees and parallelogram appear the same.
Hence, Parallelogram is the quadrilateral.

You can put the 2points into a graph in your calculator and do the slope y1~mx1+b it will give you your equation which is y= 2x - 2
