What happens to the coordinates? A. The x-coordinate remains the same and the y-coordinate changes sign. B. The y-coordinate remains the same and the x-coordinate changes sign. C. Both x and y coordinates change sign. D. Neither x nor y coordinate changes. ...
Let us look at examples of coordinates. Example 1:The point where both the axes intersect is known as the origin. Coordinates of the origin are written as O(0, 0). Example 2:In the figure below, the coordinates of point A are (3,4). It means that the point is 3 units along the...
Properties of Vertical LinesVertical lines are parallel to the y-axis. Thus, they do not intersect the y-axis. In other words, they do not have a y-intercept. The equation of a vertical line is of the form of x = a, where a is the x-intercept. Since the x-coordinates of a ...
If (2, 3) is a point on f(x), what are the coordinates of the corresponding point for each of the following transformation? a) y = 2f(x) b) y = f(x) + 1 c) y = -f(x) d) y = f(3x) e) y = f(-...

题目The point (1,1) is reflected over the x-axis. What are the new coordinates? A. (1,-1) B. (-1,1) C. (-1,-1) D. (1,1) 相关知识点: 试题来源: 解析 A。关于 x 轴对称的点横坐标不变,纵坐标变为相反数。反馈 收藏 ...
Let us learn how to plot a point on the graph by using the X- and Y-axis. For example: Let’s try to plot the point B(3,4) on the graph. Here, the x-coordinate of B is 3. So we will start from the origin and move 3 units to the right on x-axis. ...
Location is a term used to specify a particular place or geographical area. It has a physical context, like an address or GPS coordinates. Position, on the other hand, refers to the arrangement or orientation of an object or person within a particular location. It indicates a relative place...
Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height The width is 5, and the height is 3, so we know w = 5 and h = 3: Area = 5 × 3 = 15Learn more at Area of Plane Shapes....
