Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

which of the following point lies on the line y = - x

(a) (2,2)

(b) (2,-2)

(c) (-2,3)

(d) None of these

EVALUATION

Here the given equation of the line is

y = - x - - - - - (1)

CHECKING FOR OPTION : (a)

Here the given point is (2,2)

Putting x = 2 , y = 2 on Equation 1 we get

2 = - 2

Which is absurd

So the point (2,2) does not lie on the line

CHECKING FOR OPTION : (b)

Here the given point is (2, - 2)

Putting x = 2 , y = - 2 on Equation 1 we get

2 = - ( - 2 )

⇒ 2 = 2

Which is true

So the point (2, - 2) lies on the line

CHECKING FOR OPTION : (c)

Here the given point is ( - 2,3)

Putting x = - 2 , y = 3 on Equation 1 we get

- 2 = - 3

Which is absurd

So the point ( - 2,3) does not lie on the line

FINAL ANSWER

Hence the correct option is (b) (2,-2)
