mathmale · Answer

the general form of the equation of the axis of symmetry is x=-b/(2a), or $$x=\frac{ -b }{ 2a }$$

mathmale · Answer

You need to write this down, review it and remember it.

Now look at the given quadratic, y = x^2 - 8x - 3.
Identify the coefficients a, b and c.

a=?
b=?
c=?

mathmale · Answer

Now plug in the pertinent values into $$x=-\frac{ b }{ 2a}$$

mathmale · Answer

Yes. compare that to y = x^2 - 8x - 3.  

a=
b=
c=

mathmale · Answer

b is not 8 and c is not 3.  Please try again.  Watch your signs very carefully.

mathmale · Answer

Yes.  Now, using the general equation for the axis of symmetry, substitute the pertinent info and calculate the axis of symmetry for  y = x^2 - 8x - 3.

You understand, querty, that I am giving you my time, knowledge and experience.  If you're going to absent yourself from this discussion, while I wait for you to return, and then object to my telling you I need your participation, then you are crossing boundaries.  I have given you enough info with which to solve this problem already, and will now leave you to solve it.  Perhaps you could be more considerate of my time next time, and also watch your attitude towards those trying hard to help you.  Good luck.
