Quadrilateral RAPS is located at the vertices R (-4, 1), A (-3, 4), P (0, 5), S (-1, 1). Where will points R'', A'', P'', S'', be located after the quadrilateral has been reflected across the line y=x and the rotated 180 degrees about the origin?

The correct answer is: b

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
