How do you reflect a figure over a line?

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). the line y = -x is the point (-y, -x).

What does it mean to reflect across the line?

A reflection over line is a transformation in which each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the opposite side of the line. In a reflection, the image is the same size and shape as the pre-image.

What is a transformation that flips a figure over a line called?

A reflection is a type of transformation that flips a figure over a line. The line is called the line of reflection, or the mirror line. The line of reflection can be horizontal, vertical, or diagonal.

When a figure is flipped over a line?

Translation is when we slide a figure in any direction. Reflection is when we flip a figure over a line. Rotation is when we rotate a figure a certain degree around a point.

What does a rotation look like?

A rotation is a type of transformation which is a turn. A figure can be turned clockwise or counterclockwise on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same. A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.

How easily can you determine if a relation is a function?

Functions are relations that have only one output for any unique input. To tell whether a graphed relation defines a function, you can use the vertical line test.

Which is an equation of the circle whose center is?

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
