If △ABC is reflected through x = y with coordinates A(2,−1),B(4,−1),C(2,−3), what are the coordinates of △A'B'C'? A A'(2,1),B'(4,1),C'(2,3) B A'(−1,2),B'(−1,4),C'(−3,2) C A'(−2,1),B'(−4,1),C'(−2,3) D A'(−2,−1),B'(−4,−1),C'(−2,−3)

B) A’(-1,2) B’(-1,4) and C’(-3,2)

Step-by-step explanation:

When we reflected trougle trough line y=x, coordinates of x become coordinates of y, and coordinate of y become coordinate of x, for every point of triangle.

A(2,-1) then A’(-1,2)

B(4,-1) then B’(-1,4)

C(2,-3) then C’(-3,2)
