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)
