Question 746943
I am doing practice for my math 3 class.
"Equation of Tangent Line to Circle"
I have been having problems with this problem because for my 
Mtan part I don't know if a my answer is right.
I got Mtan= -3/4 I just need help to find if this is correct 
And if the slope is negative or positive.
------------------
The slope of the tangent at any point on a circle centered at the origin is
m = -x/y
m = +3/4 at point (3,-4)
