Fill in the blanks with integers, and select the correct operator ($+$ or $-$), to give an equation whose graph is the line that passes through the point $(-1,8)$ and is parallel to the graph of $4x + 3y = -8 - x - 15y.$
Rearrange the given equation as
18y = -5x - 8
The slope of a parallel line is -5/18
The equation of a parallel line through (-1,8) is
y =(-5/18)(x + 1) + 8
y = (-5/18)x - 5/18 + 8
y = (-5/18)x + 139/18
18y = -5x + 139
5x + 18y = 139
