The equation of tangent to the curve given by x=3 , y=3 at = 4 is

Options

  1. Ax+y= 2
  2. B3 x+y=3 2
  3. Cx+y=3 2
  4. Dx+3 y=3 2

Correct answer

C. x+y=3 2

Step-by-step solution

Given, x=3 , y=3 . On squaring and adding we get x²+y²=9 , which represent a circle. Equation of tangent at = 4 is aligned & x (3 4 )+y (3 4 )=9 & x+y=3 2 aligned
