Question

the point of the from (a-a) always lies on the line​

Answer 1

Answer:

${ For\;the\;line\;x+y\;=\;0. }$

${ Sum\;of\;x\;and\;y\;coordinates\;should\;be \;0. }$

${ Substituting\;co\;ordinates\;of\;the\;point. }$

${ (a,−a) in\;the\;equation\;x+y\;=\;0. }$

${ We\;get\;a+(−a)\;=a−a\;=0. }$

${ LHS\;=\;RHS. }$

${ Hence,\;(a,−a)\;satisfies\;x+y=0. }$

${ Answer\;:\;x\;+\;y\;=0\;❤. }$

Answer 2

HERe IS UR AnS:

Since, the given point (a,a) has same value of x and y-coordinates. Therefore, the point (a,a) must be lie on the line y=x...
