A line passing through the origin perpendicularly cuts the line 3x - 2y = 6 at point M. Find M?
Slope of line 3x - 2y = 6 = $$-\frac{3}{-2} = \frac{3}{2}$$
Product of slopes of two perpendicular lines = -1
Let slope of line passing through origin = $$m$$
=> $$m \times \frac{3}{2} = -1$$
=> $$m = \frac{-2}{3}$$
Equation of line passing through origin and having slope m is $$y = mx$$ (Since y intercept is zero)
=> $$y = \frac{-2}{3} x$$
=> $$3y = -2x$$ => $$2x + 3y = 0$$
Solving the above equations, we get the intersection point M = $$(\frac{18}{13} , \frac{-12}{13})$$
