Question

∆ABC is reflected about the line y = -x to give ∆A'B'C' with vertices
A'(-1, 1), B'(-2, -1), C(-1, 0). What are the vertices of ∆ABC?

a. A(1, -1), B(-1, -2), C(0, -1)

b.A(-1, 1), B(1, 2), C(0, 1)

c. A(-1, -1), B(-2, -1), C(-1, 0)

d.A(1, 1), B(2, -1), C(1, 0)

e.A(1, 2), B(-1, 1), C(0, 1)

Answer 1

Well you have to change the first number in ALL of the () so 

(-1,1) = (1,1)

(-2,-1) = (2,-1)

(-1,0) = (1,0)

so your answer is d (1, 1), B(2, -1), C(1, 0)
