5. the vertices of a triangle are p(–4, 1), q(–2, –8), and r(8, –1). name the vertices of the image reflected across the x-axis.

Reflecting across the x-axis changes the signs of the y-coordinates of the points. The reflected coordinates of vertex P are(-4,-1), the reflected coordinates of vertex Q are (-2,8), and the reflected coordinates of vertex R are (8,1).

Aline graph should be used
