Remember that to rotate a point 180° clockwise or anticlockwise, we need to apply the following rule: [tex](x,y)[/tex]⇒[tex](-x,-y)[/tex]. In other words, the new coordinates of the point will be the negative coordinates of the point before the rotation.
[tex](-10,-3)[/tex]⇒[tex][-(-10),-(-3)][/tex]⇒[tex](10,3)[/tex]
We can conclude that the coordinates of the point after a 180° clockwise rotation are: (10,3)
