What is the slope of the line x=4?相关知识点: 试题来源: 解析 This equation represents a vertical line; the y-intercept is 0, so the line is parallel to the y-axis. A vertical line has an undefined slope, because the denominator is 0. null...
Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (...
