Answer:
Slope =-1/4
Step-by-step explanation:
y=mx+n
Slope=m=(y2-y1)/(x2-x1)
A(-1,19).... x1 =-1, y1=19
B(11,16)..... x2=11, y2=16
Slope=(16-19)/(11-(-1))=(-3)/(11+1)=-3/12=-1/4
The value of Randy’s monthly allowance is $40
What is the allowance of Randy?
The allowance of Randy that he receive from his parents d dollars, hence, the total expenses and balance left after expenses is "d"

d-0.5d=8+12
0.5d=20
d=20/0.5
d=40

Answer:
Scatter Plot and Table
Step-by-step explanation:
A = 4πr² Divide both sides by 4π
A / 4π = r² Find the square root of both sides
√(A / 4π) = √(r²) Cancel out the square with the square root
√(A / 4π) = r Switch the sides to make it easier to read
r = √(A / 4π)
