Question

A figure has a vertex at (5,2). If the figure has line symmetry about the x axis, what are the coordinates of another vertex of the figure?

Answer 1

X axis is the ones that goes left and right

(x,y)

symetric about the x axis means that the vertical distance from the x axis is the same for 2 points that are symetric about the x axis

y is height

(x,y)
(5,2)
2 is height
distance from x axis
therefor the other point is -2
(5,-2)


the other vertex is at (5,-2)
