sumy is working in geometry class and is given figure abcd in the coordinate plane to reflect. the coordinates of point d are (a, b) and she reflects the figure over the line y = x. what are the coordinates of the image d? (a, -b) (b, a) (-a, b) (-b, -a)

sumy is working in geometry class and is given figure abcd in the coordinate plane to reflect. the coordinates of point d are (a, b) and she reflects the figure over the line y = x. what are the coordinates of the image d? (a, -b) (b, a) (-a, b) (-b, -a)

Answer

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the line $y = x$, the $x$ - and $y$ - coordinates are swapped.

Step2: Apply rule to point D

Given point D with coordinates $(a,b)$, after reflection over $y = x$, the coordinates of D' will be $(b,a)$.

Answer:

B. $(b,a)$
