The slope doesn't change after dilation, it would still be 2.
Step-by-step explanation:
45+90+x=180
135+x=180
x=180-135
x=45
Answer:
see explanation
Under a reflection in the line y = - x
a point (x, y ) → (- y, - x ), thus
T(- 1, 3 ) → T'(- 3, 1 )
U(- 1, 10 ) → U'(- 10, 1 )
V(- 2, 4 ) → V'(- 4, 2 )
