Hi there! The answer is C.

We can find the slope of this line by making y the subject of the equation.


`3x - 4y = 8 \\ - 4y = - 3x + 8 \\ y = ( - 3)/( - 4) x + (8)/( - 4) \\ y = (3)/(4) x - 2`

Now we can see that the slope of this line (which is positioned in front of x) is 3/4. Therefore, the slope of any line parallel to this one is 3/4 as well. The answer is C.
