(-4,4) , (2,1)
slope=(y2-y1)/(x2-x1)
slope=m =(4-1)/(-4-2)=-3/6=-1/2
(y-y1)=m(x2-x1)
y-4=-1/2(x+4)
y-1=-1/2(x-2)

Answer:
144
Step-by-step explanation:
f(4)=3*4^2
f(4)=12^2
12*12=144
So if x people were surveyed,

people owned a bike and

did not.
The difference between them is 72:

x-\frac{1}{8} [/tex] =72
so this means that

x=72
let's simplify:

x=72
and divide by 3:

x=24
and mupliply by 4:
x=96
so 96 people were surveyed
-0.127
-0.12
0.20
0.33
45/10
I think that is right

Answer:
no
Step-by-step explanation:
Put 2 where x is and see if you get a true statement.
1/2(2) -4 = 5
1 -4 = 5
-3 = 5 . . . . . . False
2 is not a solution to the equation.
__
The solution is x=18.
