Answer:
-2
Step-by-step explanation:
If you substitute x for 4, you have -4+2 to get -2.
Reflection across y=x is a special case transformation

The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices
A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)
Choice A'(1,-5)
Answer:
put x=-1, and the rest will be easy
Medida do angulo central = medida do arco interceptado
arco = 25º e ângulo central = 25º
