Answer:
A(-7 , -13) → A(-13, -7) →A''(7, -13)
B(12, -8) → B'(-8, 12) →B''(-12, -8)
C(-17, 19) → C'(19, 17) →C''(-17, 19)
Explanation:
A(-7 , -13), B(12, -8), C(-17, 19)
The rule (x,y) reflection across the line y = xis (x,y) → (y, x)
A(-7 , -13) → A(-13, -7)
B(12, -8) → B'(-8, 12)
C(-17, 19) → C'(19, 17)
The rule for a rotation by 90° about the origin is (x,y) → (-y,x)
A(-7 , -13) → A(-13, -7) →A''(7, -13)
B(12, -8) → B'(-8, 12) →B''(-12, -8)
C(-17, 19) → C'(19, 17) →C''(-17, 19)
