{{SVGRef}}
The **`y1`** attribute is used to specify the first y-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the {{SVGAttr("y")}} attribute instead.
## Elements
You can use this attribute with the SVG elements described in the sections below.
### `<line>`
For {{SVGElement('line')}}, `y1` defines the y coordinate of the starting point of the line.
<table class="properties">
<tbody>
<tr>
<th scope="row">Value</th>
<td>
<strong
><a href="/en-US/docs/Web/SVG/Content_type#length"
><length></a
></strong
>
|
<strong
><a href="/en-US/docs/Web/SVG/Content_type#percentage"
><percentage></a
></strong
>
|
<strong
><a href="/en-US/docs/Web/SVG/Content_type#number"
><number></a
></strong
>
</td>
</tr>
<tr>
<th scope="row">Default value</th>
<td><code>0</code></td>
</tr>
<tr>
<th scope="row">Animatable</th>
<td>Yes</td>
</tr>
</tbody>
</table>
```css hidden
html,
body,
svg {
height: 100%;
}
```
```html
<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
<line x1="1" x2="9" y1="1" y2="5" stroke="red" />
<line x1="1" x2="9" y1="5" y2="5" stroke="green" />
<line x1="1" x2="9" y1="9" y2="5" stroke="blue" />
</svg>
```
{{EmbedLiveSample('line', '100%', 200)}}
### `<linearGradient>`
For {{SVGElement('linearGradient')}}, `y1` defines the y coordinate of the starting point of the _gradient vector_ used to map the gradient stop values. The exact behavior of this attribute is influenced by the {{SVGAttr('gradientUnits')}} attributes
<table class="properties">
<tbody>
<tr>
<th scope="row">Value</th>

<strong
><a href="/en-US/docs/Web/SVG/Content_type#length"
