Answer:
7x +9y = -1
Step-by-step explanation:
The standard form of the equation for a line is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0.
We can get this form by multiplying the equation by 9, adding 7x+27.
y - 3 = -7/9(x +4)
9y -27 = -7x -28 . . . . . multiply by 9, eliminate parentheses
7x +9y = -1 . . . . . . . . . add 7x+27 to both sides
