The equation of this tangent line can be written in the form

Question

Find the equations of the tangent line and normal lines to the graph of the function f (x) = 12x + 7 at x = 12

a) tangent line y: ______

b) normal line y: ______

Answer 1

Since the graph of the given equation is a straight line, it has no tangent.

The slope of the normal line will be -1/12 and it must pass through (12,151).
