Which transformation represents a reflection over the y = x line? a
(x, y) → (−x, y)

b
(x, y) → (−x, −y)

c
(x, y) → (y , x)

d
(x, y) → (y, −x)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
