Points (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park:
which statement best describes the relationship between the positions of the two players?
a. dog 1's position is dog 2's position reflected across the y-axis; only the signs of the y-coordinates of dog 1 and dog 2 are different.
b. dog 1's position is dog 2's position reflected across the x-axis; only the signs of the y-coordinates of dog 1 and dog 2 are different.
c. dog 1's position is dog 2's position reflected across the x-axis; only the signs of the x-coordinates of dog 1 and dog 2 are different.
d. dog 1's position is dog 2's position reflected across the y-axis; only the signs of the x-coordinates of dog 1 and dog 2 are different.

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
