The point (not shown) with rectangular coordinates (m, n) is above line k.

Column A                   Column B
m                          n

选项 A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given

答案B

解析 直角坐标为(m,n)的点(未标出)位于直线k的上方。
解:本题的正确答案为(B)。由直线k与x轴正方向的夹角等于45。可得直线k的方程为y=x。根据一般原则,若点在直线y=x上方,则其纵坐标的值大于横坐标的值,即y>x,若点在直线y=x的下方,则其纵坐标的值小于其横坐标的值,即y
