Answer:
To be parallel, the slopes must be the same. To be perpendicular, the slopes must be opposite reciprocals (flip the fraction and multiply be -1)..
The slope of y = -3x/4 + 4 is -3/4
So C and D are correct for the first half..
The opposite reciprocal of -3/4 is 4/3, so D is the correct answer.
