Question

if p(x,y) and p(y,x) are same points then which of the following is true
1.x+y=0
2.xy=0
3.x-y=0
4.x÷y=0​

Answer 1

x-y=0

as both are same points, their X co-ordinate is equal. this gives-

X=y

x-y=0. (transpose)

Answer 2

Option 3) x - y = 0

Step-by-step explanation:

We are given the following in the question:

p(x,y) and p(y,x) are same points.

Thus, we can write that the

• Abscissa of point p is the same as the abscissa of point q
• Ordinate of point p is the same as the ordinate of point q.

Thus, we can write:

$x = y$

General form of the above equation can be written as:

$x = y\\x - y =0$

Thus, the required relation is

Option 3) x - y = 0
