In order to find the equation, let's use the slope-intercept form:
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
Where m is the slope and b is the y-intercept.
Parallel lines have the same slope, so if the slope of the given line is 2/3, the slope of the wanted parallel line is m = 2/3.
Now, to find the value of b, let's use the point (-9, 3) in the equation:
![\begin{gathered} y=(2)/(3)x+b\\ \\ 3=(2)/(3)\cdot(-9)+b\\ \\ 3=-6+b\\ \\ b=3+6\\ \\ b=9 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/j0z2rg461w7o18xeqntabrmax0n1sulk7h.png)
So the wanted equation is:
![y=(2)/(3)x+9](https://img.qammunity.org/2023/formulas/mathematics/college/dd1s9zm9luygndou68b0wiqel31aecn23e.png)
