### What is the slope of the tangent to y = sqrt[1-x] at (-8,3)?

can someone refresh me on how to solve this?

$\mbox{What is the slope of the tangent}$

$\mbox{to }\, y\, =\, \sqrt{1\, -\, x}\, \mbox{ at }\, (-8,\, 3)?$

Turn the square root into a 1/2 power. Do the Power Rule. Then differentiate the insides. Then plug in the x they give you and find the dy/dx to get the slope for that x.
