A. slope B. y-intercept C. x-intercept D. area 相关知识点: 试题来源: 解析 A。本题考查一次函数表达式中字母的含义。在方程 y = mx + b 中,'m'代表斜率(slope)。选项 B y 轴截距不符合;选项 C x 轴截距不符合;选项 D 面积不符合。反馈...
The equation of a line passing through the points (2,5) and (4,9) is y = mx + b. What is the value of m? A. 2 B. -2 C. 1/2 D. -1/2 相关知识点: 试题来源: 解析 A。根据斜率公式 m = (y2 - y1)/(x2 - x1),代入两点坐标可得 m = (9 - 5)/(4 - 2)=2。
(1) k is parallel to the line with equation y = (1-m)x + b +1. (2) k intersects the line with equation y = 2x + 3 at the point (2, 7). 选项: 答案: A 提问列表 提问: A怎么能行呢,方程斜率忘的想不多了 解答: 点赞0 ...
What is the mirror equation? What is the definition of ''g'' ? What are MACHOs? 1. Note the expression y=x^2. Which statement is most consistent with this expression? a. If x doubles, then y quadruples. b. If y doubles, then x quadruples. c. If x triples, then y doubles. ...
a也是最后一次 Also is the last time[translate] aIf you write a linear equation in the from y=mx+b, the y-intercept is (0,b). Find the y-intercepts for the equations you graphed. 如果您在写一个线性方程从y=mx+b, y拦截是(0, b)。 发现为您注标的等式y拦截。[translate] ...
y = mx – 0 + b y = mx + b Standard Form The standard form of an equation is: Ax + By = C Where A, B, and C are all whole numbers, and A is not negative. Linear Equations Based on the Number of Variables We have different linear equations based on the number of variables ...
• The equation of a line that is perpendicular is y = mx + c. What do television screens, postcards, and football goalposts have in common? They all meet at a specific angle to form perpendicular lines. So, what does “perpendicular” mean? In this article, we’ll answer that questio...
When you measure linear connections on a graph, you get a straight line that can grow, shrink, or stay the same, like horizontal or vertical lines. Mathematicians quantify linear connections using the equation:y = mx + bWhere: The dependent variable is y The variable m represents the slope...
The rule of collinear points is that any three or more points that lie on the same line when graphed together are considered collinear. This means they satisfy the equation “y = mx + b”, where m and b are the slope and y-intercept, respectively. Additionally, points can also be ...
To describe it mathematically, only the diagonal element is not 0 in the transmission matrix, as shown in Figure 15-2. Y1 = H1*X1, Y2 = H2*X2, xxx, and Yn = Hn*Xn. When obtaining the transmit signal, the receive end does not need to solve the equation. For example, if two sw...
