## What is the rule for rotation?

Rules of Rotation The general rule for rotation of an object 90 degrees is (x, y) ——–> (-y, x). For 180 degrees, the rule is (x, y) ——–> (-x, -y) For 270 degrees, the rule is (x, y) ——–> (y, -x)

## Is slope a vector or scalar?

A gradient is a vector, and slope is a scalar.

**What is the difference between a slope change and a translation?**

Answer: Translation describes movement of an object without change of size where as the change in slope describes the variation in steepness of an object. Slope is the ratio of vertical and horizontal changes between two points on a surface or line.

**What is the slope of a vector?**

Clearly the answer is that the slope is the dot product of the two vectors: slope = g · u. There are two ways to think of the slope of a linear function in a given direction. We can use a symbol, such as s, to represent distance in the given direction.

### What is the formula for translation?

In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) .

### What’s the rule for translation?

Mapping Rule A mapping rule has the following form (x,y) → (x−7,y+5) and tells you that the x and y coordinates are translated to x−7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction. Translations are also known as slides.

**How do you cite a translated book in APA in-text?**

If you cite a published translation of a source originally written in another language, include the original author’s name, the publication year of the original source, the year the translation was published, and the relevant page number in the in-text citation for both direct quotes and paraphrases (American …

**What are the 4 translations?**

There are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

## What is my slope?

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

## What is the vector equation of a line?

In general, a vector equation is any function that takes any one or more variables and returns a vector. The vector equation of a line is an equation that identifies the position vector of every point along the line. This works for straight lines and for curves.

**How are translations written?**

A translation is a type of transformation that moves each point in a figure the same distance in the same direction. Translations are often referred to as slides. You can describe a translation using words like “moved up 3 and over 5 to the left” or with notation.

**How do you find the translation vector?**

Use the translation vector shown to find the coordinates of triangle A ′ B ′ C ′ A’B’C’ A′B′C′. The vector indicates a translation of 2 units to the right and 1 unit down. We can therefore add 2 to all of the x-values and subtract 1 from all of the y-values to find the vertices of the image.

### How do you cite a translated book in APA 7?

Put the title of the book in the language you read it in the title field and put the English translation in square brackets after the title.
