Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
If lines are parallel then they have the same slope (m)
This means that the slope of the line will be 3 :
y = 3x + b
Now we must find b
To do that you must plug in the point the line goes through in the x and y of the equation.
(-6, 3)
3 = 3(-6) + b
3 = -18 + b
21 = b
y = 3x + 21
Hope this helped!
