Question

The equation x-(1/2)=-2(y+4) represents the equation of the tangent line to the graph of g(x) when x=-1. What is the value of g'(-1)?

Answer 1

put tangent line in "y=mx+b" form, then g'(x)= m since slope of tangent equals derivative

Answer 2

sorry g'(-1)

Answer 3

ok let me do that

Answer 4

I got -3 but it is not listed for my choices

Answer 5

I have -1/2, 4, -2, and 1/2 and can not be determined

Answer 6

first did you divide by -2 ?

--> y+4 = -x/2 +1/4

Answer 7

yes and then I subtracted 4 to both sides

Answer 8

I got y=(-1/2)x-(15/4)

Answer 9

good, now what is the slope?

Answer 10

slope is -1/2 oh is that what they want, man I got to get better at reading these problems

Answer 11

haha yeah

Answer 12

thanks you are the best
