问题 In a rectangular coordinate system, line k has x-intercept 4 and slope-2.

Column A                      Column B
The y-intercept of k          2
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 A
解析 在一个平面直角坐标系中，直线k在x轴上的截距为4，其斜率为2。
解：本题的正确答案是(A)。根据点斜式可以写出该直线的方程如下：Y=-2(x-4)=-2x+8。当x=0时，y=8，也即直线k在y轴上的截距为8。
