In the graph, the coordinates of the vertices of pentagon ABCDE are A(–6, –3), B(–4, –1), C(–2, –3), D(–3, –5), and E(–5, –5). If pentagon ABCDE is reflected across the y-axis, find the coordinates of E'.

The coordinates of point E are ( - 5, - 5 ). If pentagon is reflected across the y-axis then new coordinates are:  E` ( 5 , - 5 )

Answer
E'(5, -5)

Explanation
In reflection, we have a mirror line along which reflection take place.
In this case, y-axis act like a mirror line. The distance between the object and the mirror line should be same as the distance from the image and the mirror line.

The point E (-5, -5), is 5 units to the left from the mirror line. The coordinate of E after reflection would be 5 units on the right from the mirror line. 
Only the x-coordinate will change from -5 to +5. 

Coordinate of E' are; (5, -5)
