Question

The reflection point of A(-6, 10) about Y = 2 is (c, d). The value of c+d is ___.

• A. (-6,-6)
• B. (6,6)
• C. (6,-10)
• D. (-6,-10)

Answer 1

The correct option is A (-6,-6)

Reflection about Y = 0,
X - coordinate remain same.
Y - coordinate change sign.
Reflection about Y = a
X - coordinate remain same.
Y - coordinate change sign and value is reduced by 2a.
The reflection point of A(-6, 10) about Y = 2 => (-6, -6)
The value of c+d = -12
