Question

given the point (1,2)find the equation of a line on which it lies how many such equations are there​

Answer 1

This equation lies on :- x + y = 3

Where x = 1 and y = 3

Therefore, x + y = 1 + 2 = 3.

This solution can have infinite equations!

Answer 2

$\huge\red{\mid{\fbox{\tt{Answer}}\mid}}$$There \ can \ be \ infinite \ number \ of \ equations(lines)\ as\ seen\ in\ figure\ at\ the\ bottom\ of\\ answer$

$point \ (1,2)$

$\underline \underline Hence$,

$(x=1 \ , \ y=2)$

$Eg:$

$y-x=1 \ \ (2-1=0)\\x+y=3 \ \ (1+2=3)\\2x-y=0 \ \ (2(1)-2=0)$
