Answer:
63÷4=$15.75(each sibling gave which made it up to $63)
63-40=$23(amount added together-amount paid)
$23÷4=$5.75(each sibling got back)
63-5.75x
if each contributed $18:
18×4=$72(each contribute 18 dollars so multiply by 4 because 4 siblings)
72-40=32(minus 40 from amount they contributed)
32÷4=$8(divide by 4 to see what each sibling got)
Each sibling got back $8
Slope = (6-3) / -6-12) = 3 / -18 = -1/6
y = -1/6 x + b
Plug in x = -6 and y = 6 to find the value of b:-
6 = -1/6*-6 + b
b = 6-1 = 5
So the answer is m = -1/6 and b = 5
The temperature went up by 33° fahrenheit because -8+8=0 and 0+25= 25 so 8+25=33
