Question

Point T is reflected over the y-axis. Determine the coordinates of its image. T (2, 5)

a(2, -5)

b(2, 5)

c(-2, -5)

d(-2, 5)

Answer 1

T' is (-2,5)

Explanation:

To reflect a point across the y-axis, you will note the following:

1- the sign x-coordinate of the point is flipped while the value remains the same

2- both the sign and the value of the y-coordinate remain the same

We are given that:

point T is (2,5)

Applying the above:

sign of x-coordinate is flipped and value is the same :

x- coordinate of T' is -2

both sign and value of y-coordinate are the same:

y-coordinate of T' is 5

Based on the above:

T' would be (-2,5)

Hope this helps :)

Answer 2

d. (-2, 5)

Explanation:

Point T is reflected over the y-axis.

Therefore, the coordinates are (-2, 5).
