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。
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 is linear in two variables, usually x and y, that is satisfied by points of the line. The equation of line is usually found by the point-slope form y - y_1 = m (x - x_1), where m is the slope and (x_1, y_1) is a point on the line.
Ellipse - Get an introduction to the topic of an ellipse and learn about the ellipse formula along with some important equations of ellipse like the tangent equation, chord equation and more.
Explanation: The equation for a straight line is y = mx + c, where m = slope and c = y-intercept. Putting the given values in this equation we have y = x/2 + 3 The x-intercept occurs where y = 0. Thus, 0 = x/2 + 3 ; -3 = x/2 ; -6 =x 反馈 收藏 ...
