The main rule is simple: the x-value stays unchanged while the y-value flips to its opposite. Reflecting in y = x simply swaps the two coordinates over. If you reflected this over the x-axis (y = 0), your y-value would be opposite, or (5,-7). It assumes students already have reflected over the x and y axes. The rule is simple: swap the x and y values. Najla Go to channel TabletClass Math · Solve 2 to the x = 9 , what is x=? Can you solve this type of Algebra Equation? TabletClass Math•2.
