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。
