Horizontal lines in Math: Horizontal lines are the building blocks of so many 2D and 3D shapes in elementary geometry. Squares, Triangles, Rectangles, Cubes, Trapezoids, Prism are just some basic examples of shapes where we can observe horizontal lines. Horizontal lines in Coordinate Plane In c...
解析 C Points A (−2,0) and B (0,4) are on the line y=2x+4. After the rotation, we can get A1 (0,2) and B1 (4,0). Assume that the equation of the line after the rotation is y=kx+b, 4k+b=0 and b=2, ∴k=−0.5, ∴y=−0.5x+2. When x=6, y=−1....

1. **求直线L的斜率**:由点(0,0)和(1,2),斜率\( k_L = \frac{2-0}{1-0} = 2 \)。 2. **确定直线M的斜率**:因为M垂直于L,其斜率为\( k_M = -\frac{1}{k_L} = -\frac{1}{2} \)。 3. **方程形式**:直线M过原点(0,0),截距为0,故方程为\( y = -\frac{1}{2}x...
PLANE geometryJUNIOR collegesThe popular problem of the distance from a point to a line in two-dimensional coordinate geometry has been presented in many textbooks, books, and articles with multiple solutions. In this paper, we revisit this problem by presenting three interesti...
What Is a Vertical Line in Math?A vertical line is a line perpendicular to a horizontal line or the x-axis. In a coordinate plane, the y-axis is a vertical line since it is perpendicular to the x-axis, the baseline. Thus, any line that is parallel to the y-axis is vertical. A ...
In the xy-coordinate plane, the graph of x = y*y -4 intersects line l at (0, p) and (5, t). What is the greatest possible value of the slope of l?(求大神救救我TAT,这题是肿么回事.) 相关知识点: 试题来源: 解析 这是求斜率的最大值问题,可设此直线l的方程为y=kx+b,此直线又...
In geometry, a horizontal line is a line that runs from left to right and stays at the same elevation. This type of line is parallel to the x-axis on a coordinate plane, and it has a slope of 0. A horizontal line can extend infinitely in both directions.What is the equation for a...
