Sep 23, 2008 · Perpendicuar lines always have slopes that are negative reciprocals of each other. So since the given line has a slope of 2, then the new line has a slope of -1/2. You now have the slope (m = -1/2) and a point on the line, (-6,2). So write the equation using the point-slope form of a line.
If two non-vertical lines are perpendicular then the product of their gradients is −1. Conversely if the product of the gradients of two lines is −1 then they are perpendicular. EXAMPLE. Find the equation of the line which passes through the point (1, 3) and is perpendicular to the line whose equation is y = 2 x + 1. Solution

Find the equation, is standard form, with all integers coefficients, of the line perpendicular to 4x + 10y = 5 and passing through (-2,4). A perpendicular line is one that has the negative reciprocal slope of the line it is perpendicular to. So I need to know the slope of the line 4x + 10y = 5. To find it, I convert to y=mx+b form: first line:
