y  =  l 8x  - 2 l  - 7    

 

We can solve this....if the solution is positive, the the shift is to the right....if the solution is negative, the shift is to the left

 

8x  - 2  =  0     add 2 to both sides

8x  = 2            divide both sides by 8

x =  2/8  =  1/4  =   1/4 units to the right  =  axis of symmetry

 

vertex (1/4, -7),   axis of symmetry  = x  = 1/4     1/4 to the right  and  7   down

 

 

point  (11, 3)   slope  4/11

 

y  - 3   =  (4/11) (x  -  11 )
