The equation of a straight line is y = mx + b. Here m represents the ___. A. slope B. y-intercept C. x-intercept D. constant term 相关知识点: 试题来源: 解析 A。在直线方程 y = mx + b 中,m 表示斜率 slope,b 表示 y 轴截距 y-intercept,x-intercept 是 x 轴截距,constant term...
So far we have seen that a straight line can be described as a line with a constant gradient and we know how to find the gradient of any particular line from a graph of the line. In this section we shall look more closely at the co-ordinates of points on a straight line to see ...
A mathematical expression known as theequation of a straight linedescribes the relationship between thecoordinates of pointson a straight line in a Cartesian plane. There are several forms of the equation of a straight line, including the slope-intercept form,point-slope form, andstandard form. ...
We are given the coordinates of two points that lie on the straight line in Figure 2.2(a) as (0,3) and (2,5), gradient=change in ychange in x=5−32−0=22=1. To find the constant term in the expression y = mx + c, we find the value of y when the line crosse...
such as (5, 9).. then it's on the line If it doesn't.. such as (3, 2)... then it does not lie on the line What you end up with is just a straight line that goes through all the co-ordinates which share that relationship ...
If the equation of a straight line is y = 2x + 3, the slope of this line is ___. A. 2 B. 3 C. -2 D. -3 相关知识点: 试题来源: 解析 A。本题考查直线方程中斜率的确定。在直线方程 y = kx + b 中,k 表示斜率,本题中 k = 2,所以直线的斜率是 2,A 选项正确。反馈 ...
