Clue 1 and 2 only suggest that line L can meet K in either quadrant 1 or quadrant 3 as intercepts constraints apply in both the cases.Therefore meeting point p+q can be either positive or negative which can't be decided by given clues. Hence Answer E

Line L is perpendicular to line K whose equation is 3y = 4x + 12; Lines L and K intersect at (p, q). Is p + q > 0?
INFO from this: A)the intercept on x axis is (3,0) and y axis is (0,4).. B) the slope is 4/3, which tells us that y increases at a higher rate than x..
Inference: 1)Since the Line L is perpendicular to K, If its xintercept is less than 3, the two lines will intersect above xaxis and if more than 3, it will intersect below Xaxis..
lets see the statements (1) xintercept of Line L is less than that of Line K see att fig, p+q will be always negative a) in Quad III, both p and q will be ive, so p+q will be NEGAIVE.
Suff..
(2) yintercept of Line L is less than that of Line K not suff insuff..
ans A

(1) xintercept of Line L is less than that of Line K (2) yintercept of Line L is less than that of Line K Line KEquation \(3y=4x+12\) Point \((p,q)\) is on line L so \(3q=4p+12\) X intercept is \(3\) Y intercept is \(4\) Line LEquation \(yq=\frac{3}{4}(xp)\) \(3x+4y=3p+4q\) X intercept is \(\frac{3p+4q}{3}\) Y intercept is \(\frac{3p+4q}{4}\) Statement 1: xintercept of Line L is less than that of Line K \(\frac{3p+4q}{3}<3\) \(3p+4q<9\) Sum of p and q i.e., p+q is negative in all cases so sufficient.Statement 2: yintercept of Line L is less than that of Line K \(\frac{3p+4q}{4}<4\) \(3p+4q<16\) Sum of p and q i.e., p+q can be both positive and negative hence statement 2 is insufficient.A for me.

ans AThe line that you drew in the picture is wrong.It has to meet x axis at 3. And I would like someone to clarify if intercept is said to be less than 3,does that mean intercept of line should be between 3 and 3 considering the definition of intercept to be distance between origin and point where line meets axis.This is if we ignore the sign as it's the convention to denote the direction.

Hi, Thanks for pointing out.. Firstly less than 3 should mean <3 in literal sense.. now the point of intersection would be in III quad, where both x and y are ive, so the SUM will always be ive..
