The slope of the line perpendicular to line
Explanation:
When using the equation of a line, one calculates the value of
As
Hence slope of
Product of slopes of two perpendicular lines is
Hence, the slope of the line that is perpendicular to the line
graph{(3x-9y-15)(3x+y+5)=0 [-10, 10, -7.04, 2.96]}
