Question

the point of form (-a,a),where lies on x axis or y axis or y=0 or x+y=0​

Answer 1

Answer:

x+y=0

Step-by-step explanation:

because x coordinate is -a and y coordinate is a so x+y is -a+a=0

Answer 2

Answer:

For the point of the form (a,−a) to lie on the line, its co ordinates should satisfy the equation,

A) For the line x=a,

There is no y-coordinate, so it is 0

Since the point (a,−a) have y=−a, it does not lie on the line.

B) For the line y=a,

There is no x-value, so x coordinate is 0

Since the point (a,−a) have x=a



=0, it does not lie on the line.

C) For the line y=x,

Both x and y co ordinates should be equal

Since, co ordinates of the point (a,−a) are not equal, it does not lie on the line.

D) For the line x+y=0

Sum of x and y coordinates should be 0

Substituting co ordinates of the point (a,−a) in the equation x+y=0

We get a+(−a)=a−a=0

LHS = RHS

Hence, (a,−a) satisfies x+y=0.

Step-by-step explanation:

Hence answer is x+y=0
