What are the coordinates of A'B'C'?

1) Plot the points (type the ordered pair into the input bar, bottom of the page) 2) A(5,-1), B (3,-1) and C (4, -3) 3)Toolbar ImageUse the polygon tool to construct the triangle ABC 4) Toolbar ImageUse the reflection tool (9th tool over, under the reflection diagram) 5) Select the Triangle ABC, then x-axis

List the points of A"B" and C"

If a Triangle is in quadrant 2, and we reflect it over the x_axis which quadrant would the image be in?
