Which line is not perpendicular to the line 4x - 3y = 2? a)3x + 4y = 2 b)3x - 4y = 2 c)-3x - 4y = 5 d)3x + 4y = -8

Perpendicular lines are lines with slopes that are negative reciprocal of each other. we are given with the equation 4x-3y = 2 where the slope is equal to 4/3. Hence it is expected for the slope of the perpendicular line to be -3/4. the lines with this slope are  A)3x + 4y = 2, C)-3x - 4y = 5 and D)3x + 4y = -8. hence the answer is B>
