function: f(x)=x^2-12x+35
Interval [6,6.5]
How do you find the slope of the second line? Can you show this in the formula? and what would the answer be rounded to four decimal places as needed.

What second line? What first line? That is a parabola. Its slope is
df(x)/dx = 2x - 12
df(x)/dx = 2x - 12

you give an interval. If you want the slope of the line joining two points on the curve for that interval, then as you recall from your long-ago Algebra I, the slope
m = ∆y/∆x = (f(6.5)-f(6))/(6.5-6)
m = ∆y/∆x = (f(6.5)-f(6))/(6.5-6)
