Answer:
The equation of the tangent line to the curve
3 x - y = 2
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given function = f(x,y) =
...(i)
Differentiating equation (i) with respective to 'x' , we get

apply formula

<u><em>step(ii):-</em></u>
⇒ 
⇒ 
Taking common d y/d x


put At (0,2)

slope of the curve m = 3
<u><em>Step(iii)</em></u>:-
The equation of the tangent line to the curve

y - 2 = 3 ( x - 0 )
3 x - y = 2
<u><em>Final answer:-</em></u>
The equation of the tangent line to the curve
3 x - y = 2
ok so the easy way is this
