**Answer:**

**Step-by-step explanation:**

Multiply by 10 on both sides,

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
