You are given the slope of one line (m1) and you have to find the slope of another line which is perpendicular to the given line.
Input : 5 Output : Slope of perpendicular line is : -0.20 Input : 4 Output : Slope of perpendicular line is : -0.25
Suppose we are given two perpendicular line segments AB and CD. The slope of AB is m1 and line CD is m2 .
m1 * m2 = -1
From above, we can say
m2 = – 1/( m1 ) .
How does above formula work?
Let slope of line AB be m1 and we need to find slope of line CD. Below diagram gives an idea about working of formula.
