If line1 and line2 have the same slope, the two lines are parallel to one another.
Also, it's POSSIBLE that the two lines are identical. HOWEVER, the question tells us that the lines are DIFFERENT.
So, we have two lines that are PARALLEL but different

If two lines that are PARALLEL but different, then they can never have the same x-intercept, or the same y-intercept.
They can't have any points in common either.

Answer: A

Cheers,
Brent

A. None

D. I and II only
E. I, II and III

Lines with the same slope are parallel.
The lines are different (if they were the same line, could share an x-intercept, see below)

Parallel lines never intersect. Never touch.
Parallel lines have no points in common.
Another fact: Parallel lines have identical slopes and different y-intercepts.

III. l1 and l2 have exactly 1 point in common.

Parallel lines have NO points in common
-- Eliminate III
-- Eliminate options C and E

Realize that I and II are ...
Impermissible points in common.

I. Share an x-intercept:
-- that intercept point would be (x,0) -- for BOTH lines.
-- Incorrect. Parallel lines have no points in common.
To share an x-intercept is to share a point, to have that point in common.

Eliminate D

II. Share a y-intercept.
-- That point would be (0,y) -- for BOTH lines.
-- Incorrect. Parallel lines have no points in common
To share a y-intercept is to share a point, to have that point in common.

Eliminate B

ANSWER A
