Question

If point B has coordinates (−8, 1), what are the coordinates of the point when it is reflected across the y-axis and then rotated 180° about the origin?

Answer 1

Answer:

(8, 1)

Step-by-step explanation:

A reflection across the y-axis is a horizontal shift the distance to the y axis and then that same number of units to the other side.  So since you are at -8 move it 8 units to the line of reflection and then 8 more units horizontally beyond the other side.
