Web直线的方程通常是这样写的: y = mx + b (或在英国 "y = mx + c" 看下面 ) 这代表什么? y = 向上有多高 x = 向右有多远 m = 陡度(坡度)或斜率(线有多陡) b = Y截距(线与y轴的相交点) 怎样去找"m"和"b"? b 很容易:看看线在哪里与Y轴相交。 m (斜率) 则需要一些计算: m = Y 的改变 X 的改变 知道这些我们便可以写出直线的方程: 例子 1 m = 2 1 = … Web7 okt. 2014 · The coordinates of a line or point on the x-axis will always have a y coordinate of 0. The following are examples of coordinates that lie on the x-axis. (-(3pi)/2,0) (0,0) the origin (-2,0) (3,0) (pi/2,0) To find the x-intercept you would substitute in the value of 0 for y variable and then solve for the x variable.
Is $y=mx+b$ linear? - Mathematics Stack Exchange
WebThe forms y=mx+b and y=mx+a are essentially the same, except for the naming of the constant term. The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m (x-a) is essentially different … The slope-intercept form of a linear equation is where one side contains just … You're not supposed to solve the equation for y=mx+b.

Web30 aug. 2024 · The slope has to interact with `x' because it is describing the relationship between how much y changes when x changes. If x changes by a lot, the slope passes this information on to y. The intercept sits out there by itself because it is an absolute location on the line. If x changes by a lot, the y-intercept is still just the y-intercept. list of carnivores dinosaurs
