Question:

1. a) Find the slope of the tangent line to the graph of the function at the given point.

{eq}\displaystyle f(x) = - 4x + 2\ {/eq} at {eq}\ (-1,\ 6) {/eq}.

b) Determine an equation of the tangent line.

Tangent Line:

The slope of the tangent line to the graph of the given function is equal to the first derivative of the function. The slope intercept from of the tangent line is {eq}y = mx + c {/eq}.

(a)

Given

{eq}\displaystyle f(x) = - 4x + 2\ {/eq} at {eq}\ (-1,\ 6) {/eq}

Differentiating the function, we get:

{eq}\begin{aligned} f'(x) &=...
