Lines m and p are perpendicular. if the slope of line m is -3 what is the slope of line p?

Perpendicular lines have slopes that are negative reciprocals

so if m1 = -3

the perpendicular line has a slope of 1/3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
