Hint: Use the rule \(\Large (x,y) \rightarrow (-y,x)\) For example, the point (7,-5) becomes (5, 7). Basically we swap x and y, then change the sign of the first coordinate after the swap has occured original pair: (7,-5) swap x and y: (-5,7) change the sign of the first coordinate after the swap: (5,7) So that's a breakdown of how (7,-5) rotates 90 degrees counter clockwise to (5,7). The center of rotation is the origin This chart gives a list of rotation rules https://d2jmvrsizmvf4x.cloudfront.net/V4G3pprQT5evsH3JS5Zy_9D861043-9375-4DC6-85EE-5FDA751F5053.png
