Consider the following. f'(x) Function f(x): Find the slope of the given line. slope = Line Determine the slope of any line parallel to the given line. slope Find f'(x). y = x + y = 0 Find the point on f(x) where the tangent line is parallel to the given line. (x, y) = Find an equation of the line tangent to the graph of f(x) and parallel to the given line.
