Let

AB

be the intercept of the line

y = x

the circle

{x^2} + {y^2} - 2x = 0

. Then, the equation of the circle with

AB

as its diameter is

View answer and explanation

Correct option: A

{x^2} + {y^2} - x - y = 0

The correct answer is A (

{x^2} + {y^2} - x - y = 0

) because it represents the equation of a circle with the intercept AB as its diameter, where A and B are the intersection points of the line and the given circle.
