If a line is perpendicular to a line that has slope m, then the slope of the perpendicular line is −1m. Answer and Explanation: The line m has the equation y=2x+1. This equation is given in slope-intercept form...
Equation (d) is perpendicular to the line in the graph. The slope of the line in the graph is {eq}m=\dfrac{rise}{run} =\dfrac{y_2-y_1}{x_2-x_1}=... Learn more about this topic: Perpendicular Line | Slope, Equatio...
Question: A certain line is defined by the equationy=5x-82What is the value of tie slope?m=What is the y-intercept of the line?b= y=x-82 What is the value of tie slope? m= What is they-intercept of the line? b=
Example: y = 2x - 1 This says that the relationship between all the x co-ordinates and all the y co-ordinates is: "get your x co-ordinate, multiply it by 2, subtract 1, and you get your y co-ordinate" So...If a pair of co-ordinates has this relationship... such as (5,...
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...
The cartesian equation of a line is (x-3)/(2)=(y+1)/(-2)=(z-3)/(5). Find the vector equation of the line.
(x2,y2) m=y2−y1x2−x1 wheremis the slope of the line After we have the slope of the line, then the equation of the line is written by using the point-slope formula as shown below- y−y1=m(x−x1) The equation of a line in the slope-intercept form- ...
The slope-intercept form of the equation of a line can be given as: {eq}y = mx +c {/eq} where '{eq}c {/eq}' is the y-axis intercept. Answer and Explanation: Given: Point, {eq}P_1 = (4.2) {/eq} Point, {eq}...
