Question

Point B, located at (-4, -7), is reflected over the y-axis. What are the coordinates of B'?

(-4, 7)
(4, -7)
(4, 7)
(-4, -7)

Answer 1

(4, -7)

Explanation:

The rule for a reflection over the y-axis is (x,y)→(−x,y). So (-4, -7)=(--4, -7) since the 2 negatives cancel out the new coordinates are (4, -7)
