V2 DS L与Y=-X交于(2,-2),问L斜率 1) 与X轴截距positive 2) 与Y轴截距positive 注意:JJ变体 选B下面是yandian同学的解释 V2 中,K=(Y+2)/(X-2) 当与X轴交点是positive的话,就是X>0,Y=0, 不能得出K是否小于0 当与Y轴交点是posotive的话,就是X=0,Y>0,此时分母为负,分子为正,所以斜率肯定小于0.

V2 给了一个表盘,平均分成8等分,然后在图上标了A,B,C,D,E五个点,问1174.。怎么怎么样的,反正就是用1174/8,然后看余数
V3钟表的那道题,interval和钟表是不一样的,只有8个,转的interval是JJ第二个版本的那个数字,结果我选的是D 如果1174/8好像是余6,如何分到ABCDE5点啊?????大家能不能解释如果问是那个字母上面的?
