Answer:
T' is (-2,5)
Step-by-step 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 :)
