Question

The vertices of a triangle are P (-4,-8) Q(-6,6) and R (1,-7). Name the vertices of the image reflected in the y-axis.

A. P’(4,8),Q’ (6,-6),R’ (-1,7)
B. P (-4,-8),Q’ (-6,6),R’ (1,-7)
C. P (4,-8),Q’ (6,6), R’ (-1,-7)
D. P (-4,8),Q’(-6,-6), R’ (1,7)

Answer 1

C

Explanation:

Here, we want to reflect over the y-axis

by reflection over the y-axis, (x,y) becomes (-x,y)

Thus, we simply are going to negate the x values of the points given

So the correct answers are;

P’(4,-8)

Q’ (6,6)

R’ (-1,-7)
