How do you reflect the line y 4?

The line y = -4 is horizontal. If a point is reflected over a horizontal line, the x-coordinate is unchanged. The point (4,5) lies 9 units above the line y = -4, so (4,5) is reflected to the point that has x-coordinate 4 and y-coordinate that is 9 units below the line y = -4, namely (4, -13).

How do you describe reflection?

A reflection is like placing a mirror on the page. When describing a reflection, you need to state the line which the shape has been reflected in. The distance of each point of a shape from the line of reflection will be the same as the distance of the reflected point from the line.

What is the image of 4 5 by taking y-axis as a mirror?

Explanation: The mirror image of the point A(4,5) on the y-axis is A'(-4,5).

What is reflection over Y?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

What is reflection over Y X?

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

Which point would map onto itself after a reflection across the line y x 4 4?

Answer:the answer is the point (-4,0),this point would map into itself when reflected in the line y= – x, this is because the point (-4,0) is in the line y= – x thus it will map onto itself when reflected as it is in touch with the mirror line which is the line y= – x.

What does it mean to reflect over Y 0?

We will discuss here about reflection of a point in the x-axis. Reflection in the line y = 0 i.e., in the x-axis. The line y = 0 means the x-axis. Let P be a point whose coordinates are (x, y). So, the y-coordinates of P’ will be – y while its x-coordinates will remain same as that of P.

How do you reflect figures?

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
