标题: prep DS 87题(87. 7824-!-item-!-187;#058&005664)求问

In the figure above, segments PQ and PR are each parallel to one of the rectangular coordinate axes. What is the sum of the coordinates of point P ?
(1) The x-coordinate of point Q is -1.
(2) The y-coordinate of point R is 1.
不知道图看不看得见= =可以看附件的图
想问问什么不能是pq平行于x轴,pr平行于y轴,这样即是两个条件都用也不确定答案? 是因为给出的图规定了吗?
