To find the distance covered along each axis, we subtract the coordinates of the two points. For the x-axis, the move from 3 to 7 results in a horizontal distance of 4 units.

For the y-axis, the move from 4 to 1 results in a vertical distance of 3 units. Even though the y-direction is downward, the total distance or “length” of the vertical shift is considered 3 units.

When a figure is reflected, its dimensions and area remain identical, meaning the shape is congruent to the original. If reflected across the y-axis, the y-coordinates stay the same, but the x-coordinates change their sign (positive becomes negative). The orientation also changes, effectively "flippRead more
When a figure is reflected, its dimensions and area remain identical, meaning the shape is congruent to the original. If reflected across the y-axis, the y-coordinates stay the same, but the x-coordinates change their sign (positive becomes negative). The orientation also changes, effectively “flipping” the image. For example, a point at (3, 4) reflected across the y-axis moves to (–3, 4). The vertical height stays the same while the horizontal side flips.

The horizontal and vertical distances form the two legs of a right-angled triangle, with AD as the hypotenuse. According to the Baudhāyana-Pythagoras Theorem, the square of the distance AD is equal to the sum of the squares of the other two sides. In this case, 4 squared (16) plus 3 squared (9) equaRead more
The horizontal and vertical distances form the two legs of a right-angled triangle, with AD as the hypotenuse. According to the Baudhāyana-Pythagoras Theorem, the square of the distance AD is equal to the sum of the squares of the other two sides. In this case, 4 squared (16) plus 3 squared (9) equals 25. Taking the square root of 25 gives a direct distance of 5 units for AD.

Any line parallel to the vertical y-axis consists of points that all share the same x-coordinate. Since point W has an x-coordinate of –5, any point H on this parallel line must also have an x-coordinate of –5, resulting in coordinates of the form (–5, y).

In a 2-D Cartesian coordinate system, the position of any point is determined by two perpendicular lines. The horizontal line is the x-axis and the vertical line is the y-axis.

In a 2-D Cartesian coordinate system, the position of any point is determined by two perpendicular lines. The horizontal line is the x-axis and the vertical line is the y-axis. These two axes cross each other at a unique point known as the origin. At the origin, no distance has been moved along either axis, so the x-coordinate and y-coordinate are both 0, represented as (0, 0).

In moving from A (3, 4) to D (7, 1), what distance has been covered along the x-axis? What about the distance along the y-axis?
To find the distance covered along each axis, we subtract the coordinates of the two points. For the x-axis, the move from 3 to 7 results in a horizontal distance of 4 units. For the y-axis, the move from 4 to 1 results in a vertical distance of 3 units. Even though the y-direction is downward, theRead more
