Write the coordinates of the vertices after a reflection across the line y = x.

P' = (-2, 3)

Q' = (0,3)

R' = (2,9)

S' = (-8,9)

Explanation:

Because you're reflecting along the line y = x, just swap the x and y places of each coordinate.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
