Line a is defined by the equation y = mx + 4.

Line b is defined the the equation y = px - 2.

If these lines intersect at point C, is either m or p greater than 0?

(1) The x intercept of line b < 0.

(2) | m | > | p |


Does the question mean that proving any one of m<0 or p<0 sufficient?? Or is it asking the status of the other as well?

Slope m or P could be botrh +ve or both negative or +ve and -ve

hence E
