That’s simple since your given the coordinate, that mean your first coordinate will be x while the other is y therefore, 1=x and 2=y.
Substitute them from the equation, and you can see the answer is (i).
Why is not (iv) counted?
Because since the line is x=1 therefore it will never pass the y axis. Its a vertical line.
If it helped, please mark brainliest or thanks! :D

YOur welcome my friend mD
:D
hey but the line does not need to cross the y axis
because the point is given as (1,2)
so it only pass the point and not the line
it has to, because you have been give both x and y coords
can you once form the graph and check because according to me 1 and 4 both are correct
Yes sure
did you find it out??
