We have the slope-intercept form of a line
![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 line have the same slope so the slope of the line that we are searching is m=3
so we will use the slope-point form
![y-y_1=m(x-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/csobd57zth7rh9k4hz9amldzpq2owf0z4j.png)
where
m=3
x1=-2
y1=-8
then we substitute the values
![y+8=3(x+2)](https://img.qammunity.org/2023/formulas/mathematics/college/na1725qswz6803pxg60aric3buy9wnx9ay.png)
