Question

Начертите координатную прямую и отметить на ней точки А (-1), В(4),С(1,5),D(-1,5). Какие из отмеченых точек имеют противоположные координаты?

Answer 1

Противоположенные C, D

Answer 2

Drawing a Coordinate Line and Identifying Points

To draw a coordinate line and mark the points A(-1), B(4), C(1,5), and D(-1,5), we can use the following coordinates:

- Point A: (-1, 0) - Point B: (4, 0) - Point C: (1, 5) - Point D: (-1, 5)

Now, let's plot these points on the coordinate line.

Identifying Points with Opposite Coordinates

After plotting the points A, B, C, and D on the coordinate line, we can see that points A and D have opposite x-coordinates but the same y-coordinate. Therefore, points A and D have opposite coordinates.

This means that the x-coordinate of point A is the negative of the x-coordinate of point D, while the y-coordinates of both points are the same.

This is the answer to the question about which of the marked points have opposite coordinates.
