We are given the graph of a line that passes through the origin. Therefore, it must be of the form:


y=mx

We also notice that the line passes through the point (x, y) = (1, 2). Replacing the point in the equation:


\begin{gathered} 2=m(1) \\ 2=m \end{gathered}

Replacing the value of "m":


y=2x

Therefore, the equation of the given line is y = 2x
