Other line y=4x%2F5

Line L, y=-%285%2F4%29x

BOTH lines contain (0,0).

Line L is perpendicular to a line with slope m=+4%2F5.
Both lines contain the origin. ->(0,0)
y=mx%2Bb-> b=0 -lines contain the origin
y=%284%2F5%29x=> a line with slope m=+4%2F5
since line L is perpendicular to this line, it will have a slope
m%5Bp%5D=-1%2Fm
m%5Bp%5D=-1%2F%284%2F5%29
m%5Bp%5D=-5%2F4
y=-%285%2F4%29x=>line L
