a triangle has vertices at b(−3, 0), c(2, −1), d(−1, 2). which transformation would produce an image with vertices b″(1, −2), c″(0, 3), d″(3, 0)?

(x, y) → (x + 1, y + 1), (x, y) → (y, x)
(x, y) → (x + 1, y + 1), (x, y) → (−x, y),
(x, y) → (x, −y), (x, y) → (x + 2, y + 2)
(x, y) → (−x, y), (x, y) → (x + 2, y + 2)

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
