Question

Find the slope of the line tangent to the
graph of ln(xy)-2x=0 when x= -1

Answer 1

(y+xy')/xy -2 =0 ===> y' =-1 ===> y'(x=-1) =-1

Answer 2

um..these are the answer choices..
1. slope = 3/2e^-2
2. slope= 3/2e^2
3. slope= 3e^-2
4. slope= -3e^2
5. slope= -3/2e^2
6. slope= -3e^-2

Answer 3

lol :P
