which line?
Hint: A&C and B&D are perpendicular
Which is the Equation of a line perpendicular to the line

B 4x-3y=5
C 3x-4y=3
D 3x+4y=5

For Ax + By = C
the slope is -A/B
e.g. the slope of 3x - 4y = 3 is -3/-4 or 3/4
remember that if a given line has slope of k/l, then the perpendicular line will
have slope of - l/k ,
e.g. 6/7 vs -7/6
