我们知道,方程y=kx+b称为直线的斜截式方程,其k是直线的斜率,b是直线的纵截距,类似地,方程x=my+n也是直线的方程,其中m是直线的斜率的倒数,n是直线的横截距,对直线的斜截式方程的应用,我们都非常熟悉,而对后者及应用常常被忽视. We know that the equation y = kx + b is called a linear truncated equation, where k is the slope of the line and b is the longitudinal intercept of the line. Similarly, the equation x = my + n is also a straight line equation where m is The reciprocal of the slope of the straight line, n is the linear cross-section, we are very familiar with the application of straight-line oblique equation, and the latter and applications are often overlooked.
