Question

1. In the graph, the coordinates of the vertices of quadrilateral ABCD are A(-27,17), B(24,14), C(19,3) and D(-7,7) If quadrilateral EFGH is created as the image of quadrilateral ABCD reflected across the x-axis, find the coordinates of the vertex located at point E.

A. (-27,-17)
B. (-24,-14)
C. (-19,-3)
D.(-7.-7)

2. In the graph, triangle EFG is a reflection of preimage triangle ABC. AB=46 unitts, BC=44 units, and AC=10 units. Find the length of FG.

A: FG=10 units
B: FG= 44 units
C: FG= 46 units
D: FG= 56 units

3.Describe the change that occurs to the coordinates of a vertex of a figure when it is reflected across the y-axis.

A.The sign of the x-coordinate changes; the y-coordinate stays the same.
B.The x-coordinate stays the same; the sign of the y-coordinate changes.
C.Both coordinates stay the same.
D.The sign of each coordinate changes.

Please help? D':

Answer 1

1- E is reflected to A across the x-axis so its coordinate will be (-27,-17)

2- We get FG when we reflect BC across the x-axis. Therefore, FG = BC = 44.

3- It is A.
