A line passes through the origin and has a slope of –3. The equation of the line that is perpendicular to the first line and passes through the point (3, 4) is y = 1/3x + 3

A line passes through the point (–2, 4), and its y-intercept is (0, –6). The equation of the line that is perpendicular to the first line and passes through the point (5, –4) is y = 1/5x - 5

First we need to find out the slope of the first line m = (-6 - 4)/(0 + 2) = -5; therefore, the slope for the required line is 1/5. Since the line pass through (5, -4), in point slope form is y + 4 = 1/5(x - 5), rewritten in slope intercept form is y = 1/5x - 5
