**y=x10 is a direct variation**, because everything you do to y will result in a similar change in x .

### What equation represents a direct variation?

The general equation for direct variation is the linear equation, **y = kx** where k is the constant of variation (or constant of proportion). The constant of variation is also the slope of the line representing the relationship between input and output.

### What is direct variation used for?

A direct variation, also called direct proportion is **a relationship between two variables x and y** that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x.

### Is xy 10 a direct variation?

**y=x10 is a direct variation**, because everything you do to y will result in a similar change in x .

### What is direct variation on a graph?

Direct variation describes **a simple relationship between two variables** . We say y varies directly with x (or as x , in some textbooks) if: y=kx. for some constant k . This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

### How do you know if it is a direct variation?

If you have a table of values and want to see if it represents a direct variation, just **create ratios from the table.** **If all the ratios are the same, then you have a direct variation**!

### What is not direct variation?

**Equations of the form y = kx + b where b is a number other than zero** are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx. K is the constant of variation it is the slope of the line y = kx.

### Is YX 5 a direct variation?

It is **not a direct variation**.

### How do you write a direct variation?

N/A

- The equation for direct variation is y=kx.
- The equation for direct variation is y=kx.
- The equation for direct variation is y=kx.
- The equation for direct variation is y=kx.
- We can just plug 4 in for y and 2 in for x to find the value of k.

### What is direct variation and inverse variation?

Direct variation is a linear function defined by an equation of the form y = kx when x is not equal to zero. Inverse variation is a nonlinear function defined by an equation of the form xy = k when x is not equal to zero and k is a nonzero real number constant.

### What bonds do nonmetals form?

In general, **covalent bonds** form between nonmetals, ionic bonds form between metals and nonmetals, and metallic bonds form between metals.

### What is animal fibre and plant Fibre?

Difference Between Animal Fibres and Plant Fibres**Animal fibres are extracted from animals**. Plant fibres are extracted from plants. They are made of proteins. They are made up of cellulose. Animal fibres have comparatively lesser strength.

### What are the types of Fibres Class 7?

There are two types of fibres, i.e. **natural fibre and man-made fibre (nylon, rayon)**. Some of our clothes are made from yarn derived from the animal fibre.

### Do nonmetals gain or lose electrons to form positive ions?

Metals tend to lose electrons and form positively charged ions called cations. Non-metals tend to **gain electrons** and form negatively charged ions called anions.

### How do metals and nonmetals gain stability?

If a metal and a nonmetal interact, then **an ionic bond** will result. These types of bonds involve the metal donating it(s) valence electron(s) to a nonmetal. As the electronic transfer occurs, both atoms will achieve more stabile confirmations.

### Which among the following pairs are animal fibre?

**Wool and silk** are animal fibres.

### How many animal fibres are there?

Ans: The \(**23**\) primary types of animal fibres are present. Textile fibres obtained from animals are known as animal fibres. They are basically animal hair, fur, skin, or secretions.

### What ions are formed when nonmetals gain electrons?

non-metal atoms gain electrons to form **negative ions (anions )**

### Do nonmetals form cations or anions?

Metals form cations while **non-metals form anions**.

### Which is an animal fibre answer?

Answer: Animals fibres are **silk and wool**.

### What is plant and animal fibres?

Plant fibres include seed hairs, such as cotton; stem (or bast) fibres, such as flax and hemp;leaf fibres, such as sisal; and husk fibres, such as coconut. Animal fibres include wool, hair and secretions, such as silk.
