A it is......2 lines never intersect meaning they r || to each other...so the slope of the line in ques has to be equal to the slope of the given line. Offcourse, assuming, all lines r in a plane and not in 3D. I think DS instructions says that all lines in plane unless otherwise indicated.

Thats corrdct but the Q asks "What is the slope of the staight line "

they want a particular value right ?

its nto asking whether the slope is parallel

m = 1 ...as given line y = x+2 has slope of 1...so does the line in ques.

I am not in support of the answer.
How can we conclude THAT if lines do not intersect they will surely be parallel

two lines are parallel if and only if they have no common intersection

1.What is the slope of the staight line

1) The given straight line and straight line Y=X+2 does not intersect
2) The given straight line and the straight line Y=-X+3 intersects

I don´t have the OA for this question but I´d like to discuss it.
I think OA is A.

1) the lines are parallel---Sufficient.
2) from here we don´t know the slope,it can have a positive or negative gradient.Insufficient.



A, by definition does not interesect = parallel, to be parallel they have to have the saem slope.
