(1) The line p intercepts the y-axis at the point (0, 3).
(2) The line q intercepts the x-axis at the point (3, 0).


I've never practiced co-ordinate geometry, not even for my actual gmat


p interesects at Y axis
q at x axis

now p and q can both be downwards/upwards

(E) imo


not sure

1) line p can intersect (0,3) both with a positive slope and a negative slope.
2) line q can intersect (3,0) both with a positive slope and a negative slope.
1+2) Still unknown whether both lines intersect the axes with a positive slope or negative slope

= E (i think)
