The slopes of perpendicular line segments are 1/2 and d/3 What is the value of d?

d=-6
d=-3/2
d=3/4
d=6

Respuesta :

perpendicular slopes have a product of -1, thus   [tex]\bf \cfrac{1}{2}\cdot \cfrac{d}{3}=-1[/tex]

solve for "d"
apologiabiology
perpendicular lines have slopes that multiply to get -1
so

1/2 times d/3=-1
d/6=-1
times both sides by 6
d=-6
