If Line K in th xy-plane has equation y=mx+b, where m and b are constants, what is the slope of k?
1) K is parallel to the line with equation y = (1-m)x + b + 1
2) K intersects the line with equation y=2x+3 at the point (2,7))
[spoiler]OA A. Though I understood why B is insufficient, will option B be sufficient if the question is reworded that K and y=2x+3 are perpendicular (and hence we know from K's slope the relation m1*m2=-1).
Also, which other additional/new info will make B sufficient. Thx [/spoiler]
