A) \[ac>0,bc>0\]
B) \[c>0\,and\,bc<0\]
C) \[bc>0\,and/or\,ac>0\]
D) \[ac<0\,and/or\,bc<0\]
Correct Answer: D
Solution :
[d] If the line meets the x- and y-axes at A and B, then\[A\equiv (-c/a,0)\],\[B\equiv (0,-c/b).\]The line will pass through the first quadrant if \[-c/a>0and/or-c/b>0\] i.e., \[ac<0and/orbc<0\]
