A line equation can be written in slope-intercept form, whih is
[tex]y=mx+b[/tex]
where m represents the slope and b represents the y-intercept.
Since our line passes through the origin, we already know that b = 0. To find the slope of our line, we can evaluate any of the points that belongs to our line on the slope-intercept form then solve it for m. The point (12, 200) for example belongs to our line. Evaluating this point on the form, we have:
[tex]\begin{gathered} (200)=m(12)+(0) \\ 200=12m \\ m=\frac{200}{12} \\ m=\frac{50}{3} \end{gathered}[/tex]
therefore, our line equation is
[tex]y=\frac{50}{3}x[/tex]
The correct answer is option A.
