The point (a, b) is rotated about the origin 180° and then reflected in the x-axis. What coordinate best describes
the resulting transformation of the point?

Please answer, it’s a bonus question be i need help

P(a, b)-P(–a,–b)–P(–a,b)

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
