# slope of secant line?

Consider the function f(x) = √x and the point P(4,2)

Find the slope of each secant line

(line passing through Q(1, f(x)))

(line passing through Q(5, f(x)))

(line passing through Q(8, f(x)))

Consider the function f(x) = √x and the point P(4,2)

Find the slope of each secant line

(line passing through Q(1, f(x)))

(line passing through Q(5, f(x)))

(line passing through Q(8, f(x)))

x^2 + (4 root 3)^2 = (2x)^2 simplify x^2 + 48 = 4x^2 subtract x^2 from both sides and you get

48= 3x^2 divide by 3 and you get 16=x^2 4=x for your unknown leg and 8=2x for your hypotenuse.
