Triangle abc is reflected over the y axis. what are the coordinates of the reflected triangle

A'(-1,3),B'(-4,5),C'(-3,1).

Step-by-step explanation:

The coordinates of the vertex of the given triangle are A(1,3) ,B(4,5) ,C(3,1).

When a point is reflected along the y axis the y value f the point (x,y) remains the same while x changes its sign.

Point (x,y) will have the reflected pint x'(-x,y)

The reflected points along the y axis are:

A(1,3) A'.(-1,3)

B(4,5)B'(-4,5)

C(3,1)C'(-3,1)
