Answer:
y = 3/4x+7
Step-by-step explanation:
The slope is 3/4 and a point is (-8,1)
We can use point slope to make an equation for the line
y-y1 = m(x-x1)
y-1 = 3/4(x--8)
y-1 = 3/4(x+8)
y-1 = 3/4x +6
Add 1 to each side
y-1+1 = 3/4 x+6+1
y = 3/4x+7
This is in slope intercept form (y=mx+b)
You would multiply 2x4 and 3x4 and it would be 8/12 so that leaves you with 4 twelths left.

Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
