Answer:
(-5,9)
Step-by-step explanation:
When rotating 270 degrees clockwise you would need to switch x and y and make y negative so you would have (x,y) and then after 270 degrees it would be (-y,x). Or another way to solve it is by finding the opposite reciprocal of (9,5) and then find the point you are rotating around and make an equation for it. Assuming you are rotating from the origin you should get the equation y=-5x/9 as -5/9 is the opposite reciprocal and thus the slope. Then to find the exact point you need to find the same distance from your new line to origin so it would be the same exact distance from (9,5) to origin. This would give you the same answer (-5,9)
