x - 6y = -18
P1 = (-5, -4)
1.- Solve the equation for y to find the slope
x - 6y = -18
-6y = -x - 18
y = -1/-6x - 18/-6
y = 1/6 x + 3
2.- Find the slope
The slope is the coefficient of x
slope = m = 1/6
3.- Find the equation of the line
y - y1 = m(x - x1)
y + 4 = 1/6(x + 5)
y + 4 = 1/6x + 5/6
y = 1/6x + 5/6 - 4
y = 1/6 x + 5/6 - 24/6
y = 1/6x - 19/6
4.- Result
y = 1/6x - 19/6
