Watch this video to learn how to reflect a shape across the x-axis.
To just change the locations of points in a graph along x-axis, there is a single step involved. Consider A=(-5,-8), B=(-3,-4), C=(-8,-3), D=(-6,1) a graph which is drawn with four points, three in third quadrant((-8,-3),(-5,-8),(-3,-4)) and one point in second quadrant(-6,1). Just you multiply the elements by -ve term than all the elements are interchanged into A=(5,8), B=(3,4), C=(8,3), D=(6,-1).
