Fin equation of the tangent line at the given value of x on the curve.

2xy - 2x + y = -14, x = 2

This is what i try.==>

2y + 2xdy - 2 + dy = 0

2*2y-2*2+y = -14

5y=-10

y=-2

2*(-2) +2*2dy -2 + dy = 0

5dy = 6

dy=5/6

But this isnt answer what i need?

Thats correct, i did typing mistake, but answer need to be one of these:

1. y = (6/5)x - 22/5

2. y = (5/6)x - 22/6

3. y = -(6/5)x + 22/5

4. y = -(5/6)x + 22/6

my guess is answer # 3
