- The x- and y-intercepts of line ℓ are both positive.
选项:
A、Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B、Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C、BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D、EACH statement ALONE is sufficient.
E、Statements (1) and (2) TOGETHER are not sufficient.

A
提问：
老师，x-intercept是X轴的截距的意思吗？我想的是条件1，XY截距有四种情况，所以选的C。截距在数学里面分正负号的？那如果怎么表述就是不分正负号只考虑距离？
