Reflect the triangle =(-1,-2), 4(1,1), V(4,- 3) across the line y = x a)T(-1,2), U(1,1), V(4,3) ) b)T(1,2), U (-1,1), c) V (-4,3) c)T(-2,-1),U(-1,1), V (-3,4)
d)T(1, - 2), U(- 1, - 1),V(- 4, - 3)

see explanation

Step-by-step explanation:

Under a reflection in the line y = x

a point (x, y ) → (y, x ) , thus

(- 1, - 2 ) → (- 2, - 1 )

(1, 1 ) → (1, 1 )

(4, - 3 ) → (- 3, 4 )

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
