Ok, so what do we have to find?

The set is infinite as there are infinitely many straight lines that can pass through a given point. Set builder form:
[tex]
L=\{(y-y_1)=m(x-x_1):m\in R\}\\
[/tex]
Roster form,
[tex]
L=\{(y-y_1)=5(x-x_1),(y-y_1)=\pi(x-x_1).....\}
[/tex]
but you write little and use elipsis or etc symbol "..."
Is it said in the question, that represent it in roster form?
yes
represent in roster using elipsis
Then just put any value of m in this equation seperate by commas, and use elipsis.
like {1,2,3,4,5,6,...}
no
then how
Now see it.
thanks
