SOLUTION

If the triangle is reflected across the line y = x, then

We will switch the coordinates of y to that of x and, the coordinates of x to that of y

The coordinates for the points of the triangle are

[tex]\begin{gathered} Q(-5,\text{ 2)} \\ \\ R(0,\text{ 5)} \\ \\ S(-1,\text{ 2)} \end{gathered}[/tex]

The reflection becomes

[tex]Q^{\prime}=(2,-5),R^{\prime}=(5,0),S^{\prime}=(2,-1)[/tex]

Therefore option D is the correct answer
