Which of the following equations represents a line that is perpendicular to the line described by the equation 4x + 3y = 9?	Choose the correct choice from the following options:	A) 3x + 4y = 18	B) 3x – 4y = 24	C) 5y – 3x = 26	D) 1.5y + 2x = 18	E) 8x – 6y = 24
Perpendicular lines have slopes which are negative reciprocals of each other.   The line 4x + 3y = 9 in slope-intercept form is y = -(4/3)x + 3   The slope of this line is -4/3.   The slope of a perpendicular line is 3/4.   3x - 4y = 24 in slope-intercept form is y = (3/4)x - 6   The answer is 3x – 4y = 24.
