A point P(3, 4) is reflected in line x + 3 = 0. Then the image of P is
(-8, 4)
(-9, 4)
(-6, 4)
(-5, 4)
Given line x + 3 = 0 ⇒ x = -3
Let P' (x, 4) be the image of P(3, 4), Using midpoint formula
x+32=−3 ⇒x=−9
Complete the following table :

(b) (4, 2) Reflection x-axis ---------
(c) --------- Reflection in y-axis (0, 6)
(d) (6, -6) ----------------- (-6, 6)
(e) (4, -8) ------------------ (-4, -8)
