C

You need to know both m, slope and c, y-intercept to place a line (defined by y=mx+c) in the quadrant system.

OA is A, since slope is negative

With A...Couldn't we have two cases with a negative slope?

Case 1) Goes from Quad 2 --> Quad 4
OR
Case 2) Goes from Quad 3 --> Quad 4 (Sloping Downward)?

Case 2 will still go through quadrant II - it is an infinite line. Negative slope line always goes through quadrants II and IV.

1. y-interncept of K = -6 and slope of K negative, so k goes DOWNWARD, from II to IV. You can answer the question, yes, K go through II quandrant

2. y-interncept of K = -6 and slope of K possitive, so k goes UPWARD, from III to I quandrant. You can answer the question, NO, K does NOT go throught II quandrant.

So is SO. :lol:

how can it go because if it intercept in -6 in Y axis then it can only go through 3 and 4
