In a xy plane, the equation of a line is #x+3y=12#. What is an equation of a line that is perpendicular to it?
The equation of a straight line in slope (
In this example we are given the equation:
For two straight lines to be perpendicular to eachother their slopes
Hence the straight lines perpendicular to the line with a slope of
For example, the line perpendicular to the given line with the same intercept is
