so 
Answer:
I believe the answer is b as my friend dream said
Step-by-step explanation:
Y= -(1/2)x+b
to get m you flip it so it is the reciprocal
-2= -(1/2)(6)+b
-2= -3+b add 3 on each side
1=b
y= -(1/2)x+1
Formula for finding the area of a triangle is
A= BH/2. So plus in 12 in A for area. Plug 6 in B for base. And solve
(12)*2=(6h/2)*2
(24)/6=(6h)/6
4=h
So the height of the triangle is 4 ft
