To reflect a point (x, y) over the x-axis, the x-coordinate remains the same, and the y-coordinate changes its sign. The vertices of triangle ABC are A(6,4), B(8,1), and C(6,1).
A'(6, -4)
B'(8, -1)
C'(6, -1)
To translate a point (x, y) 4 units right and 5 units down, we add 4 to the x-coordinate and subtract 5 from the y-coordinate. The vertices of DEFG are D(-6, 7), E(-4, 7), F(-4, 2), and G(-6, 2).
D'(-6 + 4, 7 - 5) = D'(-2, 2)
E'(-4 + 4, 7 - 5) = E'(0, 2)
F'(-4 + 4, 2 - 5) = F'(0, -3)
G'(-6 + 4, 2 - 5) = G'(-2, -3)
The coordinates of the reflected triangle A'B'C' are A'(6,-4), B'(8,-1), and C'(6,-1).
The coordinates of the translated quadrilateral D'E'F'G' are D'(-2,2), E'(0,2), F'(0,-3), and G'(-2,-3).
