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=$$\sqrt{}x$$+2. Let Q be the point (x, $$\sqrt{}x$$+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
I

3. The attempt at a solution
I was using the formula : m$$_{}pq$$= x$$_{}2$$ -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,
