Question

You reflect triangle pqr, with verticles p(-2 -4) q(-3 -1) and r(-4 -4) across the y-axis to get triangle p'q'r' what are the cooridinates of triangle p'q'r'

Answer 1

see explanation

Explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , thus

p(- 2, - 4 ) → p'(2, - 4 )

q(- 3, - 1 ) → q'(3, - 1 )

r(- 4, - 4 ) → r'(4, - 4 )
