1. The coordinate grid shows the intersection of line 1 and line 2.
Which transformations on lines 1 and 2 will result in a pair of lines intersecting at the same angle measurements as
those formed by the intersection of line 1 and line 2?
A. The reflection of line 1 over the x -axis and the translation of line 2 four units up.
B. The reflection of line 1 over the x -axis and the translation of line 2 four units to the left.
C. The reflection of line 1 over the x -axis and the reflection of line 2 over the line
D. The reflection of line 1 over the x -axis and the reflection of line 2 over the line

2. Lines m and n are graphed on the coordinate grid shown.
Part A
Lines m and n are translated 4 units down and 8 units left. Sketch a graph to represent the new location of lines m and
n . Label the new location of line m as line e and the new location of line n as line f .
Part B
Lines m and n are reflected across the x -axis. Explain the effect this reflection has on the lines. Has the distance
between the lines changed?
Part C
Are the lines m and n parallel, perpendicular, or intersecting lines? Describe what happens to the lines after a
clockwise rotation of 90? is applied to the lines.
Be sure to complete ALL parts of the task.

How to reflect across a line? Reflections in coordinate geometry x-axis reflection. A reflection across the x-axis changes the position of the y-coordinate of all the points in a figure such that (x, y) becomes (x , -y). y-axis reflection. A reflection across the y-axis changes the position of the x-coordinate of all the points in a figure such that (x, y) becomes (-x, y). Reflections across the line y = x. ...
