# Math Help - Slope using Diff quotient

1. ## Slope using Diff quotient

use the difference quotient to calculate the slope of the secant line thru the points (1, f(1)) and (3, f(3))

#25 f(x)=(x-2)^2

i assume the difference quotient you're using is: $\frac {f(x + h) - f(x)}h$

in that case, the slope of the secant line will be: $\frac {f(3) - f(1)}2$.
