Answer:
Problem #2 on the worksheet.
Explanation:
So to start this off, draw the line y = -1 on the graph.
That line is going to be the "mirror" of this reflection.
Now each and every point is going to be opposite when it reflects along that line.
Point A = (-2, 5) will reflect and become (-2, -7)
What we did here is just move the point down (because y = -1 is reflecting downwards aka across x-axis). It is located 6 units above the line, so move it 6 units down.
Same with points B and C.
After these transformations, your new triangle will have these points.
Point A-prime: (-2, -7)
Point B-prime: (-2, -3)
Point C-prime: (1, -3)
Hope this helps! :)
