Using Coordinate Rules : 

Using Coordinate Rules Find the coordinates of the image Use the rule to change the coordinates Graph the new image

Try This : 

Try This Use the rule (x,y)(-y,x) on the figure below -1 -4 -1 -6 -6 -6

Try This : 

Try This Use the rule (x,y)(y,-x) on the figure below 1 4 1 6 6 6

Try This : 

Try This Use the rule (x,y)(-x,-y) on the figure below 4 -1 6 -1 6 -6
