The slope - intercept form of the line equation is $\"\"$ , where $\"\"$ is slope and $\"\"$ is y - intercept.

$\"\"$

Observe the graph of the function :

The graph touches the x - axis at $\"\"$ and the graph touches the y - axis at $\"\"$ .

Thus, the y - intercept is $\"\"$ .

Let he points are $\"\"$ and $\"\"$ .

Slope $\"\"$ .

Substitue the slope $\"\"$ and y - intercept $\"\"$ in slope - intercept form. \ \

$\"\"$ .

Thus, the line equation is $\"\"$ . $\"\"$

The line equation is $\"\"$ .
