find the slope of the tangent line to the graph of f(x)= x^-9 ( is it -9x^-10) ?

OpenStudy (amistre64):

drop and subtract; yes

OpenStudy (liizzyliizz):

so its right?

OpenStudy (amistre64):

that is the equation for the slope of the curve for any given point; all you need to complete it is some point

OpenStudy (liizzyliizz):

it didnt have a point given. however for the next question- find the equation of the tangent line of f(x)= x^-9 it doest give points (-1,-1) so then what would i do next?
