How do you reflect over Y 3?

The line y = 3 is a horizontal line so we know our reflected point will be (1, y’). The original point (1, 2) is just one unit less (or one unit away below it) from the line y = 3, so our reflected point will be one unit away above it, giving us (1, 4).

How do you reflect coordinates?

Every point of a flipped image is the same distance from the mirror line as the original shape. To reflect a given point over the x-axis, simply multiply the y coordinate of the point by -1. To reflect over the y-axis, just multiply the x coordinate of the point by -1.

What are coordinates of point A?

In the figure below, point A lies on the y-axis and point C lies on the x-axis. When a point lies on an axis, one of its coordinates must be zero. Point A–If you look at how far the point is from the origin along the x-axis, the answer is zero. Therefore, the x-coordinate is zero.

What are the coordinates of a point that is the mirror image of point (- 3/5 in Y axis?

mirror image of point P(-3,-5) in y – axis is : P(3,-5).

What is the coordinate rule for reflection?

What is the rule for a reflection across the Y axis? The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

What reflect Y means?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). the y-axis is the point (-x,y). Reflect over the y = x: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.

How do you find the coordinate of the reflected image?

In general, when reflecting a point in the origin, if the coordinate of the preimage is (x , y), then the coordinate of the reflected image is (-x, -y) When reflecting a point across any line, just keep this mind. The distance between the point and the line and the reflected point and the line is exactly the same.

How to find a reflection image using the lines?

How to find a reflection image using the lines y = x and y = -x. Reflection of a point across the line y = x. The coordinate of point P is (1, 4) and the coordinate of the reflected image P’ is (4, 1) The coordinate of point A is (-5, -2) and the coordinate of the reflected image A’ is (-2, -5)

How to find the point reflection of an axis?

This calculator helps you to find the point reflection A, for the given coordinates of A (x,y). Just select an axis from the drop-down and enter the coordinates, the point reflection calculator will show the result.

How do you reflect a point across a line with -X?

Therefore, swap the x-coordinate with the y-coordinate and then take the opposite of both coordinates. In general, when reflecting a point across the line y = -x, if the coordinate of the preimage is (x , y), then the coordinate of the reflected image is (-y, -x)
