6x Find the slope of the graph of the function g(x) = at ( - 1, -3). Then find an equation for the line tangent to the graph at that point. X+3 . . . 6x The slope of the graph of the function g(x) = x +3 at ( - 1, -3) is (Type an integer or a simplified fraction.) 6x The equation for the line tangent to g(x) = x+3 at ( - 1, -3) is y =
