Observe the graph:

\

\

The line passes through origin, the $\"\"$ – intercept of the graph is $\"\"$ .

\

Consider the points on the graph are $\"\"$ and $\"\"$ .

\

Find the slope:

\

$\"\"$

\

$\"\"$ (Formula for the slope)

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Simplify)

\

Therefore,the slope is $\"\"$ .

\

Find the equation:

\

The slope-intercept form of line equation is $\"\"$ . \ \

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$

\

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

\

Hence, option (D) is right choice.
