Write the equation of the line that satisfies the given condition: contains the origin and is perpendicular to the line 8 x - 9 y = -5.
A) 9 x + 8 y = 5
B) 9 x - 8 y = 5
C) 9 x - 8 y = 0
D) 9 x + 8 y = 0

Question

Quizplus · Accepted Answer

The slope of the given line is 8/9. A line perpendicular to it will have a slope of -9/8. Since it passes through the origin, its y-intercept is 0, leading to the equation 9x + 8y = 0.
