The equation of the normal to the curve y= x at the point (0,0) is

Options

Ax=0
B) y=0
Cx+y=0
Dx-y=0

Correct answer

C. x+y=0

Step-by-step solution

Given curve y= x Slope of normal to the curve at point (0,0) =- ( d x d y )_ 0,0 =- ( 1 x )_ 0,0 =-1 Equation of normal to the curve at point (0,0) is y-0=- l (x-0) x+y=0
