In the rectangular coordinate system, line k passes through the points (0, 0) and (4,8); line m passes through the points (0,1) and (4,9).
Column A Column B
The slope of line k The slope of line m
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
C
解析
在一个平面直角坐标系中,直线忌通过(0,0)和(4,8)两点,直线m通过(0,1)和(4,9)两点。
解:本题的正确答案为(C)。Slope=(y1-y2)/(x1-x2), so, Slope(k)=(8-0)/(4-0)=2; Slope(m)=(9-1)/(4-0)=2
