The lines perpendicular to each other are :

  • A and C

because

  • slope of line A = 1/2

  • slope of line C = -2

and for two lines to be perpendicular, their product should be equal to -1,

  • [tex] \dfrac{1}{2} \times - 2[/tex]

  • [tex] - 1[/tex]

therefore we can say that the two perpendicular lines are C and A.
