Answer 4

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
