Hello,
Let's put this 9x + 8y =3 in y=mx+b form:
y=-9/8(x)+3/8
So we know the slope is -9/8
Now plug in (2,-4) to find b:
-4=-9/8(2)+b
Solve for b to get:
b=-7/4
Now we know the equation is:
y=-9/8(x)-7/4
make sense?

Since the 
and 
terms are on the same side of the equals sign, take the opposite of the coefficient on and divide it by the coefficient on to calculate the slope of the line represented by the given equation. Parallel lines have equal slopes. Use the point-slope form of an equation of a line:
 )
where )
are the coordinates of the given point and 
is the calculated slope.
Rearrange your equation into slope-intercept form.
