Question

karen performs a transformation on parallelogram syntax error from line 1 column 49 to line 1 column 73. unexpected 'mathsize'. that is plotted on a coordinate grid to form parallelogram syntax error from line 1 column 49 to line 1 column 73. unexpected 'mathsize'. the image of each point is shown in the table below. which best describes the transformation karen performed?

Answer 1

The transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.

The table is given as:

Original  point ---- Image

A (-4,-1)                  (1,-4)

B (-7,-6)                 (6,-7)

C (-14, -6)              (6,-14)

D (-11, -1)               (1,-11)

From the table, we can see that;

The coordinates are swapped, and the new x-coordinate is negated.

This represents 90 degrees counterclockwise rotation across the origin.

The rule of this transformation is:

$(x,y) \to (-y,x)$

i.e.

$(-4,-1) \to (1,-4)$

$(-7,-6) \to (6,-7)$

$(-14, -6) \to (6,-14)$

$(-11, -1) \to (1,-11)$

Hence, the transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.
