Question

На координатной прямой отмечены точки M(6)M(6) и N(-2)N(−2) . Чему равна координата точки RR , симметричной точке MM относительно точки NN ? Запиши ответ числом.

Answer 1

Ответ:

Пошаговое объяснение:

1ая точка 6, вторая точка -2

разница 8

-2 - 8 = -10

точка будет расположена на этой же прямой на координатах (-10;-10)

Answer 2

Finding the Coordinate of the Point R

To find the coordinate of the point R, which is symmetric to the point M with respect to the point N, we can use the formula for finding the reflection of a point across a line.

The formula for finding the reflection of a point (x, y) across a line with equation y = mx + c is:

x' = (x - m(y - c))/(1 + m^2) y' = (2m(x - c) + y(1 - m^2))/(1 + m^2)

In this case, the line is the x-axis, which has an equation of y = 0. Therefore, the formula simplifies to:

x' = x y' = -y

Since the point M has coordinates (6, 0), the reflection of M across the x-axis is the point R with coordinates (6, 0).

Therefore, the coordinate of the point R, which is symmetric to the point M with respect to the point N, is 6.
