#### Answer

$y=\frac{2}{7}x$

#### Work Step by Step

The given line has a slope of $\frac{2}{7}$ and a y-intercept of $(0,0)$. We can write this line in the slope-intercept form $y=mx+b$ (where m is the slope of the line, and the point $(0,b)$ is the y-intercept).
In this case, $m=\frac{2}{7}$ and $b=0$.
Therefore, $y=\frac{2}{7}x+0=\frac{2}{7}x$.
