Homework Help: Need help

  1. Feb 10, 2008 #1
    I have not seen math in years and just started claculus last week.
    1. The problem statement, all variables and given/known data

    The point p(25,7) lies on the curve y=[tex]\sqrt{}x[/tex]+2. Let Q be the point (x, [tex]\sqrt{}x[/tex]+2).
    Find the slope of the secant line PQ for the following values of x:
    If x=25.1, the slope of PQ is:

    2. Relevant equations

    3. The attempt at a solution
    I was using the formula : m[tex]_{}pq[/tex]= x[tex]_{}2[/tex] -1 /X-1 and substituting x for 25.1 and then performed division.
    Im new to the site and I'm getting used to the formatting so excuse my errors,
