IMO A.
Line with a negative slope must intesect quadrant II.

This line must be y= -x/6 + m(intrecept)
in quadrant II, x values are negative and y values are positive.

So a line that intersects quadrant 2 must have points like that

y1=-x1/6 +m>0
-x1/6>-m (as x1 is negative -x1/6 must be positive)
So if m is positive than inequation holds, if m is negative one can find an -x1 value that is greater than -m for all values of -m.
Thus, 1) is sufficient

2 is unsufficient. e.g. line k => y=-6 or for any positive value of n line k => y=-6 + nx
