When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:
From the diagram:
L(3,1), M(4,3), N(5,3) and P(4,1).
Using the reflection rule, you can find coordinates of image points:
L'(1,3), M'(3,4), N'(3,5) and P'(1,4).
As you can see, these are coordinates of vertices of the figure C.
Answer: correct choice is option 3 - figure C.
we have that
we know that
If two lines are parallel
then
their slopes are equals
and
if two lines are perpendicular
then
the product of their slopes is equal to
step 1
find the slope of the line segment AB
step 2
find the slope of the line segment CD
therefore
the answer is
Line segments AB and CD are perpendicular
