Find the slope of tangent to
y =

at x=4

slope =

Step-by-step explanation:

To find the slope, differentiate with respect to x and evaluate at x = 4

is the measure of the slope of the tangent at x = a

Differentiate each term using the power rule

(a ) = na

Given

y = + 2

  = 4 + 2, hence

= - 4 +

= - +

At x = 4

= - +

                                   = - + =

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2
