Lines n and p lie in the xy-plane. Is the slope of line n less than the slope of line p ? (1) Lines n and p intersect at the point (5,1). (2) The y-intercept of line n is greater than the y-intercept of line p. 答案是C,想問一下為何不是B -- Char~~~~Lie~~~~ 超爽的~~ 可以還給嘔嗎? 撿到一顆腎! ◢▅◣ ███◤◥▂ \ / Φ §tacokuo ˊ██ Char~~~~Lie~~~~ ▂▅ ─╯∕ ▅▂ 改ψjeans1020 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.164.148.9

只有y截距無法決定斜率
