Que:- In the Rectangular Co-ordinate system shown above (it was normal XY plane with 4 Qudrants in it), does the line K intersect quadrant II?
a) The slope of K is -1/6
b) The y-intercept of K is -6
OA - A
Can someone please explain this to me. I think C should be the answer as from A we cannot determine the the value constant (y-intercept) present in the equation of line k (y= -1/6x + c).
I agree with A.
We don't know the value of C.
C can be +ve or zero or -ve
When c is +ve -->Line K intersect quadrants I,II, IV
When c is -ve -->Line K intersect quadrants II,III, IV
When c is zero -->Line K intersect quadrants II,IV
In all these cases.. K intersect quadrants II and IV.
So it should be A.
