Step-by-step explanation:
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 = \frac{ - 3}{ - 4} x + \frac{8}{ - 4} \\ y = \frac{3}{4} x - 2](https://tex.z-dn.net/?f=3x%20-%204y%20%3D%208%20%5C%5C%20-%204y%20%3D%20-%203x%20%2B%208%20%5C%5C%20y%20%3D%20%5Cfrac%7B%20-%203%7D%7B%20-%204%7D%20x%20%2B%20%5Cfrac%7B8%7D%7B%20-%204%7D%20%5C%5C%20y%20%3D%20%5Cfrac%7B3%7D%7B4%7D%20x%20-%202)
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.
