Afive year old is having her birthday party at the local bowling alley. explain two different counts that her parents may estimate in preparation for that party. one should be an over-estimate and the other may be an under-estimate.

translate k to n and reflect across the line containing jk.

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 )
