Question

What are the new vertices of parallelogram DEFG if the parallelogram is reflected across the vertical line x= -2, also graphe O A. D'=(-4,5), E' =(-1,3), F = (-1,-4), G' = (-4,-2) O B. D' = (5,1), E' = (3,-1), F = (-4,-1), G' = (-2,-1) OC. D'= (1,5), E = (-1,3), F =(-1,-4), G' = (1,-2) O D.D' = (1,5), E = (3,3), F = (3.-4), G' = (1,-2)

Answer 1

By looking at the graph we can see that the y coordinate of the points are unaffected, and the x coordinates have added the distance of the reflection to the image point.

D = (-5,5) ; D' = (-5+6, 5) = (1,5)

E= (-3,3); E' = (-3+2,3) = (-1,3)

Correct option:

C. D'= (1,5), E = (-1,3), F =(-1,-4), G' = (1,-2) O D.
