Answer
$y-3=2(x-3)$
Work Step by Step
The equation of a line in the point-slope form is the following:
$y-y_1=m(x-x_1)$, where $m$ is the slope and the point $(x_1,y_1)$ is on the graph.
In order to determine the equation of a line, we have to calculate the slope.
For this, we can use the rule, that parallel lines have the same slopes.
Here, a parallel line is $y=2x$.
In this form, the slope can be seen as the coefficient of $x$, here $2$
Therefore our line's slope is also $m=2$
Therefore, using the point $(3, 3)$ and the slope $2$, the equation can be written as:
$y-3=2(x-3)$
