What are the coordinates of d’ when the quadrilateral is reflected across the line y=x?

D'(1,3)

Step-by-step explanation:

If a function is reflected across the line y=x, then the rule of reflection is

From the given graph it is clear that the vertices of figure are A(1,2), B(2,4), C(4,3) and D(3,1).

We need to find the coordinates of D’ when the quadrilateral is reflected across the line y=x.

Using the above rule we get

Therefore, the coordinates of D' after reflection are (1,3).

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
