Hello, I need to find the tangent line to the grapg of y=g(x) at x=5 if g(5) = -3 and g'(5) = 4 Can anybody give me a hint how I can do that? Thanks

So, y-g(5)=g'(5)(x-5) y+3=4(x-5) y+3=4x-20 y=4x-23 Is that correct?
that is correct. The equation for a line can be written like gives you the slope of the line (k) and gives you a point in the tangent line (x and y) Knowing that,
