Which of the following equations represents a line that is perpendicular to the line described by the equation 2x + 3y = 12?  Pick:
A) 4x + 2y = 5	B) 5x + y = 7	C) 3x - 2y = 8	D) 4x - 3y = 9	E) x + y = 10
Perpendicular lines have slopes which are negative reciprocals of each other.   The line 2x + 3y = 12 in slope-intercept form is y = -(2/3)x + 4   The slope of this line is -2/3.   The slope of a perpendicular line is 3/2.   3x - 2y = 8 in slope-intercept form is y = (3/2)x - 4   The answer is 3x - 2y = 8.
