## What is reflection 6th grade?

A reflection flips a figure over a line to create a mirror image. When a point is reflected over the. y. -axis, the.

## How do you reflect points?

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).

**What are the 4 rules for reflection?**

Reflection on a Coordinate Plane

- Reflection Over X Axis. When reflecting over (across) the x-axis, we keep x the same, but make y negative.
- Reflection Over Y Axis. When reflecting over (across) the y-axis, we keep y the same, but make x-negative.
- Reflection Across Y=X.
- Reflection Across Y=-X.

**What is a reflection number?**

You can reflect a figure across a line to get a mirror image of the figure. Every point is the same distance from the line of reflection, and the reflection, or mirror image, is the same size as the original image.

### How do you plot a reflection?

How To: Given a function, reflect the graph both vertically and horizontally.

- Multiply all outputs by –1 for a vertical reflection. The new graph is a reflection of the original graph about the x-axis.
- Multiply all inputs by –1 for a horizontal reflection.

### What do you need to know about reflection in math?

Every point is the same distance from the line of reflection, and the reflection, or mirror image, is the same size as the original image. Tell students that they will use the x – and y -axes on the coordinate plane to reflect points across the x – and y -axes. Have pairs work through the problem and then discuss it as a class.

**What do students learn in reflection of coordinates?**

Students previously learned about the coordinate plane and how to plot ordered pairs. For the Do Now, each student will receive a piece of graph paper and a ruler. Create a coordinate plane and plot: (-2,4) (5,-7) (3,9) (-6,-6). After about 5 minutes, I will call students to the board to explain and show how they plotted the coordinates.

**When do students name the vertices of a reflection?**

Students reflect a figure across one of the axes on the coordinate plane and name the vertices of the reflection. As they are working, students look for and make use of structure to identify a convention for naming the coordinates of the reflected figure. When point ( m, n) is reflected across the y -axis, the reflected point is (− m, n ).

#### What does swbat mean for reflection of coordinates?

SWBAT reflect coordinates. Students reflect points over the x and y axes. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
