摘要:
We show that when one line approaches a vertical line and another line approaches a horizontal line, the product of the slopes can approach any real number or +oo or — oo or nothing, thus clarifying preceding statements of Subramaniam and Das. We stress that the slope of a vertical line does not exist and explain why all these discussions are very useful in the classroom.
