In the xy-coordinate plane, the slope of line l is
            .  Does line l pass through the point (-2/3,1/2)

 

(1)  Line l passes through the point (4,4).

 

(2)  Line l passes through the point (-4,-2).

这道题是选D，脑壳有点发昏，我想问的是条件1和条件2分别都不能满足l过(-2/3,1/2），那是不是因为都是否定了题目，所以也分别可以成立？

翻各位給我讲解一下，脑壳有点糊了。。谢谢。。等待中
