Reflect point A(-1,3) in
a) x axis
b) line y = 4
give the coordinates of the final image

Given:

The point is A(-1,3).

To find:

The coordinates of the final image. If the given point reflected in

(a) x-axis

(b) line y=4.

Solution:

(a)

If a figure reflected across the x-axis, then

Using this rule, we get

Therefore, the coordinates of the final image are A'(-1,-3).

(b)

If a figure reflected across the line y=4, then

Using this rule, we get

Therefore, the coordinates of the final image are A'(-1,5).
