Question

(Write the relation between the slopes of
two lines, when they are perpendicular to
each other.
​

Answer 1

Answer:

The slopes of any pair of perpendicular lines are in negative reciprocal relationship. ... Line one is in point slope form y=mx+b, slope m=4. Line two is in the form (y-y1) =m(x-x1), slope m=-1/4. 4 and -1/4 are negative reciprocals to each other, and therefore, these two lines are perpendicular.
