If two lines are paralle then their slopes are equal.

since given equation y=3x-1 and  required line are parallel therefore

slope of required line=3  and

required line passes through (-3,-5)

Thus equation of line is

`y+5=3(x+3)`

`y+5=3x+9`

`y=3x+4`

Thus the line passes through (-3,-5) and parallel to y=3x-1 is y=3x+4 .
