Iwant to know the answer to his question

ok, maybe you really don't know how to do this, but this is just being plain lazy. any way,

see the B's that have a little 2 on them? image that the other B's also have the same thing, but it's a one.

see all the numbers above the B's? add them all

And you get 6

now take one of your Bs and slap the six on like so

and there's your answer

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 )

answer:

c) the x-coordinate of the center of the circle increases by 3
