Which of the following equations represents a line that is perpendicular to the line described by the equation 3x + 4y = 10?
Choose the correct option.
A) 3x + 4y = 12 B) 3x – 4y = 20 C) 4y – 3x = 22 D) 1.5y + 2x = 18 E) 8x – 6y = 24
Perpendicular lines have slopes which are negative reciprocals of each other.   The line 3x + 4y = 10 in slope-intercept form is y = -(3/4)x + 2.5   The slope of this line is - 3/4.   The slope of a perpendicular line is 4/3.   8x - 6y = 24 in slope-intercept form is y = (4/3)x - 4   The answer is 8x – 6y = 24.
